ANSWER: Correct Ups and Downs Learning Goal: To apply the law of conservation of energy to an object launched upward in the gravitational field of the earth. In the absence of nonconservative forces such as friction and air resistance, the total mechanical energy in a closed system is conserved. This is one particular case of the law of conservation of energy. In this problem, you will apply the law of conservation of energy to different objects launched from the earth. The energy transformations that take place involve the object’s kinetic energy and its gravitational potential energy . The law of conservation of energy for such cases implies that the sum of the object’s kinetic energy and potential energy does not change with time. This idea can be expressed by the equation , where “i” denotes the “initial” moment and “f” denotes the “final” moment. Since any two moments will work, the choice of the moments to consider is, technically, up to you. That choice, though, is usually suggested by the question posed in the problem. First, let us consider an object launched vertically upward with an initial speed . Neglect air resistance. Part A As the projectile goes upward, what energy changes take place? ANSWER: v = 6.8 ms K = (1/2)mv2 U = mgh Ki + Ui = Kf + Uf v Correct Part B At the top point of the flight, what can be said about the projectile’s kinetic and potential energy? ANSWER: Correct Strictly speaking, it is not the ball that possesses potential energy; rather, it is the system “Earth-ball.” Although we will often talk about “the gravitational potential energy of an elevated object,” it is useful to keep in mind that the energy, in fact, is associated with the interactions between the earth and the elevated object. Part C The potential energy of the object at the moment of launch __________. ANSWER: Both kinetic and potential energy decrease. Both kinetic and potential energy increase. Kinetic energy decreases; potential energy increases. Kinetic energy increases; potential energy decreases. Both kinetic and potential energy are at their maximum values. Both kinetic and potential energy are at their minimum values. Kinetic energy is at a maximum; potential energy is at a minimum. Kinetic energy is at a minimum; potential energy is at a maximum. Correct Usually, the zero level is chosen so as to make the relevant calculations simpler. In this case, it makes good sense to assume that at the ground level–but this is not, by any means, the only choice! Part D Using conservation of energy, find the maximum height to which the object will rise. Express your answer in terms of and the magnitude of the acceleration of gravity . ANSWER: Correct You may remember this result from kinematics. It is comforting to know that our new approach yields the same answer. Part E At what height above the ground does the projectile have a speed of ? Express your answer in terms of and the magnitude of the acceleration of gravity . ANSWER: is negative is positive is zero depends on the choice of the “zero level” of potential energy U = 0 hmax v g hmax = v2 2g h 0.5v v g h = 3 v2 8g Correct Part F What is the speed of the object at the height of ? Express your answer in terms of and . Use three significant figures in the numeric coefficient. Hint 1. How to approach the problem You are being asked for the speed at half of the maximum height. You know that at the initial height ( ), the speed is . All of the energy is kinetic energy, and so, the total energy is . At the maximum height, all of the energy is potential energy. Since the gravitational potential energy is proportional to , half of the initial kinetic energy must have been converted to potential energy when the projectile is at . Thus, the kinetic energy must be half of its original value (i.e., when ). You need to determine the speed, as a multiple of , that corresponds to such a kinetic energy. ANSWER: Correct Let us now consider objects launched at an angle. For such situations, using conservation of energy leads to a quicker solution than can be produced by kinematics. Part G A ball is launched as a projectile with initial speed at an angle above the horizontal. Using conservation of energy, find the maximum height of the ball’s flight. Express your answer in terms of , , and . Hint 1. Find the final kinetic energy Find the final kinetic energy of the ball. Here, the best choice of “final” moment is the point at which the ball reaches its maximum height, since this is the point we are interested in. u (1/2)hmax v g h = 0 v (1/2)mv2 h (1/2)hmax (1/4)mv2 h = (1/2)hmax v u = 0.707v v hmax v g Kf Express your answer in terms of , , and . Hint 1. Find the speed at the maximum height The speed of the ball at the maximum height is __________. ANSWER: ANSWER: ANSWER: Correct Part H A ball is launched with initial speed from ground level up a frictionless slope. The slope makes an angle with the horizontal. Using conservation of energy, find the maximum vertical height to which the ball will climb. Express your answer in terms of , , and . You may or may not use all of these quantities. v m 0 v v cos v sin v tan Kf = 0.5m(vcos( ))2 hmax = (vsin( ))2 2g v hmax v g ANSWER: Correct Interestingly, the answer does not depend on . The difference between this situation and the projectile case is that the ball moving up a slope has no kinetic energy at the top of its trajectory whereas the projectile launched at an angle does. Part I A ball is launched with initial speed from the ground level up a frictionless hill. The hill becomes steeper as the ball slides up; however, the ball remains in contact with the hill at all times. Using conservation of energy, find the maximum vertical height to which the ball will climb. Express your answer in terms of and . ANSWER: Correct The profile of the hill does not matter; the equation would have the same terms regardless of the steepness of the hill. Problem 10.14 A 12- -long spring is attached to the ceiling. When a 2.2 mass is hung from it, the spring stretches to a length of 17 . Part A What is the spring constant ?

ANSWER: Correct Spring Gun A spring-loaded toy gun is used to shoot a ball straight up in the air. The ball reaches a maximum height , measured from the equilibrium position of the spring. s = 0.67 m kg N/m cm v = 2.2 ms H Part A The same ball is shot straight up a second time from the same gun, but this time the spring is compressed only half as far before firing. How far up does the ball go this time? Neglect friction. Assume that the spring is ideal and that the distance by which the spring is compressed is negligible compared to . Hint 1. Potential energy of the spring The potential energy of a spring is proportional to the square of the distance the spring is compressed. The spring was compressed half the distance, so the mass, when launched, has one quarter of the energy as in the first trial. Hint 2.

ANSWER: Correct Introduction to Potential Energy Learning Goal: Understand that conservative forces can be removed from the work integral by incorporating them into a new form of energy called potential energy that must be added to the kinetic energy to get the total mechanical energy. The first part of this problem contains short-answer questions that review the work-energy theorem. In the second part we introduce the concept of potential energy. But for now, please answer in terms of the work-energy theorem. Work-Energy Theorem The work-energy theorem states , where is the work done by all forces that act on the object, and and are the initial and final kinetic energies, respectively. Part A The work-energy theorem states that a force acting on a particle as it moves over a ______ changes the ______ energy of the particle if the force has a component parallel to the motion. W = -1900 J W W = -1800 J Kf = Ki + Wall Wall Ki Kf Choose the best answer to fill in the blanks above: ANSWER: Correct It is important that the force have a component acting in the direction of motion. For example, if a ball is attached to a string and whirled in uniform circular motion, the string does apply a force to the ball, but since the string's force is always perpendicular to the motion it does no work and cannot change the kinetic energy of the ball. Part B To calculate the change in energy, you must know the force as a function of _______. The work done by the force causes the energy change. Choose the best answer to fill in the blank above: ANSWER: Correct Part C To illustrate the work-energy concept, consider the case of a stone falling from to under the influence of gravity. Using the work-energy concept, we say that work is done by the gravitational _____, resulting in an increase of the ______ energy of the stone. Choose the best answer to fill in the blanks above: distance / potential distance / kinetic vertical displacement / potential none of the above acceleration work distance potential energy xi xf ANSWER: Correct Potential Energy You should read about potential energy in your text before answering the following questions. Potential energy is a concept that builds on the work-energy theorem, enlarging the concept of energy in the most physically useful way. The key aspect that allows for potential energy is the existence of conservative forces, forces for which the work done on an object does not depend on the path of the object, only the initial and final positions of the object. The gravitational force is conservative; the frictional force is not. The change in potential energy is the negative of the work done by conservative forces. Hence considering the initial and final potential energies is equivalent to calculating the work done by the conservative forces. When potential energy is used, it replaces the work done by the associated conservative force. Then only the work due to nonconservative forces needs to be calculated. In summary, when using the concept of potential energy, only nonconservative forces contribute to the work, which now changes the total energy: , where and are the final and initial potential energies, and is the work due only to nonconservative forces. Now, we will revisit the falling stone example using the concept of potential energy. Part D Rather than ascribing the increased kinetic energy of the stone to the work of gravity, we now (when using potential energy rather than work-energy) say that the increased kinetic energy comes from the ______ of the _______ energy. Choose the best answer to fill in the blanks above: ANSWER: force / kinetic potential energy / potential force / potential potential energy / kinetic Kf + Uf = Ef = Wnc + Ei = Wnc + Ki + Ui Uf Ui Wnc Correct Part E This process happens in such a way that total mechanical energy, equal to the ______ of the kinetic and potential energies, is _______.

A force of magnitude , applied parallel to the incline, pulls the block up the plane at constant speed. v = 6.2 ms x = 4m x = 0 m x = 0 m x = 4 m x = 4 m x = 4 m v = 4.6 ms w F Part A The block moves a distance up the incline. The block does not stop after moving this distance but continues to move with constant speed. What is the total work done on the block by all forces? (Include only the work done after the block has started moving, not the work needed to start the block moving from rest.) Express your answer in terms of given quantities. Hint 1. What physical principle to use To find the total work done on the block, use the work-energy theorem: . Hint 2. Find the change in kinetic energy What is the change in the kinetic energy of the block, from the moment it starts moving until it has been pulled a distance ? Remember that the block is pulled at constant speed. Hint 1. Consider kinetic energy If the block's speed does not change, its kinetic energy cannot change. ANSWER: ANSWER: L Wtot Wtot = Kf − Ki L Kf − Ki = 0 Wtot = 0 Correct Part B What is , the work done on the block by the force of gravity as the block moves a distance up the incline? Express the work done by gravity in terms of the weight and any other quantities given in the problem introduction. Hint 1. Force diagram Hint 2. Force of gravity component What is the component of the force of gravity in the direction of the block's displacement (along the inclined plane)? Express your answer in terms of and . Hint 1. Relative direction of the force and the motion Remember that the force of gravity acts down the plane, whereas the block's displacement is directed up the plane. ANSWER: Wg L w w ANSWER: Correct Part C What is , the work done on the block by the applied force as the block moves a distance up the incline? Express your answer in terms of and other given quantities. Hint 1. How to find the work done by a constant force Remember that the work done on an object by a particular force is the integral of the dot product of the force and the instantaneous displacement of the object, over the path followed by the object. In this case, since the force is constant and the path is a straight segment of length up the inclined plane, the dot product becomes simple multiplication.

Sex, Gender, and Popular Culture Spring 2015 Look through popular magazines, and see if you can find advertisements that objectify women in order to sell a product. Alternately, you may use an advertisement on television (but make sure to provide a link to the ad so I can see it!). Study these images then write a paper about objectification that deals with all or some of the following: • What effect(s), if any, do you think the objectification of women’s bodies has on our culture? • Jean Kilbourne states “turning a human being into a thing is almost always the first step toward justifying violence against that person.” What do you think she means by this? Do you agree with her reasoning? Why or why not? • Some people would argue that depicting a woman’s body as an object is a form of art. What is your opinion of this point of view? Explain your reasoning. • Why do you think that women are objectified more often than men are? • How does sexualization and objectification play out differently across racial lines? • Kilbourne explains that the consequences of being objectified are different – and more serious – for women than for men. Do you agree? How is the world different for women than it is for men? How do objectified images of women interact with those in our culture differently from the way images of men do? Why is it important to look at images in the context of the culture? • What is the difference between sexual objectification and sexual subjectification? (Ros Gill ) • How do ads construct violent white masculinity and how does that vision of masculinity hurt both men and women? Throughout your written analysis, be sure to make clear and specific reference to the images you selected, and please submit these images with your paper. Make sure you engage with and reference to at least 4 of the following authors: Kilbourne, Bordo, Hunter & Soto, Rose, Durham, Gill, Katz, Schuchardt, Ono and Buescher. Guidelines: Keep your content focused on structural, systemic, institutional factors rather than the individual: BE ANALYTICAL NOT ANECDOTAL. Avoid using the first person or including personal stories/reactions. You must make sure to actively engage with your readings: these essays need to be informed and framed by the theoretical material you have been reading this semester. Keep within the 4-6 page limit; use 12-point font, double spacing and 1-inch margins. Use formal writing conventions (introduction/thesis statement, body, conclusion) and correct grammar. Resources may be cited within the text of your paper, i.e. (Walters, 2013).

Question 3 (1 point) In Rotter’s model, the behavior that is most likely to be performed in a given situation is Question 3 options: the one that has been reinforced. the one with the strongest behavior potential. the one for which a model has been reinforced. the one most consistent with the person’s self concept. Question 4 (1 point) Marlene’s desk becomes so messy that on occasion she cannot find an important paper she is looking for. After several incidents in which she suffered the consequences of not finding a paper she needed (such as a homework assignment), she learned to organize and straighten her desk. Marlene learned this new behavior through which operant conditioning procedure? Question 4 options: positive reinforcement negative reinforcement punishment extinction Question 5 (1 point) Colleen is trying to decide which of two events to enter in the school track meet. She thinks she would have a better chance of winning in the 100 meter race, but decides to enter the 10,000 meter race instead. According to Rotter’s theory, Question 5 options: her generalized expectancies determined this decision. the reinforcement value of winning the 10,000 meter race is greater than the reinforcement value of winning the 100 meter race. the decision illustrates that the behavior potential does not always determine behavior. she must have been reinforced for winning the 10,000 meter race in the past. Page 1 of 3 ________________________________________ . Question 6 (1 point) A woman complains to her therapist that lately she hasn’t “felt like herself.” The therapist plans to use a behavior modification treatment by altering the rewards and punishments in the woman’s environment. What is likely to be the first step the therapist takes in setting up this treatment? Question 6 options: Define the woman’s problem in terms of observable behaviors. Interview people the woman knows to determine the extent of the problem. Obtain baseline data for how often and when the problem occurs. Determine what in the woman’s past has been responsible for causing this problem. Question 7 (1 point) According to Bandura, we learn many behaviors by observing models. Whether or not we perform these behaviors depends on Question 7 options: our expectations for rewards and punishments. the reinforcement value of the rewards. generalized expectancies. whether we are children or adults. Question 8 (1 point) According to Bandura, people are most likely to change their behavior when they believe Question 8 options: the therapist has the ability to change them. following the treatment program can lead to the desired outcome. they are capable of engaging in the behaviors needed to bring about the desired outcome. they have chosen the type of treatment themselves. Question 9 (1 point) From his observations of cats escaping from a “puzzle box” to obtain a piece of fish, Thorndike developed a theory that is known as Question 9 options: the law of operant conditioning. the law of effect. the law of consequences. the law of association. Question 10 (1 point) Edward Thorndike observed cats learning to escape from boxes to obtain a piece of fish. He derived from these observations the “law of effect.” This was an early statement of Question 10 options: classical conditioning. operant conditioning. shaping. stimulus generalization. ________________________________________ . Question 11 (1 point) According to the behaviorist position, why don’t classically conditioned phobias extinguish after the pairing is removed? Question 11 options: People expect that the feared object will continue to hurt them. The fear and associated behaviors, such as running away from the feared object, often are reinforced. The fear of the original object generalizes to additional objects. The feared object has lost all of its reinforcement value. Question 12 (1 point) John’s mother wants her son to stop crying every time something goes wrong. Following a psychologist’s advice, she stops running to comfort John whenever the boy starts crying over some minor incident. After a few weeks, she notices that John cries much less often than he used to. This is an example of Question 12 options: positive reinforcement. negative reinforcement. punishment. extinction. Question 13 (1 point) According to Bandura, behavior modification procedures Question 13 options: are most effective when used in conjunction with other types of treatments. provide people with a method to change themselves once they have decided to do so. are not as effective as behavior therapists claim. are no more effective than providing clients with no treatment. Question 14 (1 point) The behavioral approach to personality postulates that personality is Question 14 options: the combination of environmental circumstances and unconscious impulses. a function of how we feel about conditions in the environment. the consistent patterns of behavior we engage in. the result of inherited predispositions to behave in certain ways. Question 15 (1 point) A woman shows no interest in socializing with other people. How might a behaviorist explain this behavior? Question 15 options: The woman does not believe that she can interact effectively with other people. The woman has not been reinforced enough for engaging in social behavior. The woman experiences anxiety in social situations and uses her asocial style as a defense against this anxiety. The woman is either high in social anxiety or low in sociability.

Prepare a five page (minimum) paper along with a cover page, a summary (as noted below) and reference page, on a Landmark Supreme Court Case that dealt with Aboriginal rights in Canada within the past 25 years (e.g. choose from those covered in Oct. 22rd class or another one if you find one that was not addressed but fits the criteria of a Supreme Court case that dealt with Aboriginal rights in Canada within the past 25 years). You can complete the assignment as a written paper (1.5 space/12 point font Times New Roman x 4 pages) or you can use points. In either method, provide a detailed response to each of the questions listed below. In addition to the paper that you will submit for grading, prepare a one page summary/cover page that you will present in class on November 12th and share with the other ANIS3006 students (handout, there are 18 students registered in the course). Frame your paper within the context of the following quotes: “Even when we win we lose.” (Chief Dean Sayers, Batchewana First Nation, commenting on Anishinabe experience in Canadian courts). “For the master’s tools will never dismantle the master’s house. They may allow us to temporarily beat him at his own game, but they will never enable us to bring about genuine change. Racism and homophobia are real conditions of all our lives in this place and time. I urge each one of us here to reach down into that deep place of knowledge inside herself [himself] and touch that terror and loathing of any difference that lives here. See whose face it wears. Then the personal as the political can begin to illuminate all our choices.” (Audre Lorde, feminist) In your paper, answer this broader question: How has the case you’ve selected served to advance Anishinabe rights in Canada? Describe what was gained and consider at what cost (“Even when we win, we lose.”) Address the following, and add anything that you find significant about the case, its process, its outcome and subsequent impact: • What was the basis of the court case? • What happened (e.g. Anishinabe people charged, by who, what charge)? • Who took the issue to court (who was the claimant, against who)? • What was the basis of the claim (be specific)? How was the issue framed/presented? • Who supported the court case (locally, regionally, nationally)? How did they support it? What was the impact of their support (e.g. political, financial, public awareness, protests, etc.)? • How long did it take from initiating the claim to decision (specific dates, chronology)? • What happened? What was the lower court’s decision? How did the case move through to the Supreme Court? What was the final Supreme Court decisions? • What did the Supreme Court’s decision mean in terms of Aboriginal rights in Canada? (What was gained, what was lost)? • Anything else of note relating to the case, its process or outcome. • Answer if and how the Supreme Court decision formed the basis for changes in Canadian government policies or practice concerning Aboriginal Peoples in Canada. In other words, what has the outcome of the Supreme Court decision been to date?
