A car is traveling with constant velocity along a highway. The driver notices he is late for work, so he stomps down on the gas pedal and the car begins to speed up. The car has just achieved double its directions at time step 0, time step 10 = initial velocity when the driver spots a police officer behind him and applies the brakes. The car then slows down, coming to rest at a stoplight ahead. Draw a complete motion diagram for this situation. PROBLEM-SOLVING STRATEGY 1.1 Motion diagrams MODEL: Represent the moving object as a particle. Make simplifying assumptions when interpreting the problem statement. VISUALIZE: A complete motion diagram consists of: The position of the object in each frame of the film, shown as a dot. Use five or six dots to make the motion clear but without overcrowding the picture. More complex motions may need more dots. The average velocity vectors, found by connecting each dot in the motion diagram to the next with a vector arrow. There is one velocity vector linking each set of two position dots. Label the row of velocity vectors . The average acceleration vectors, found using Tactics Box 1.3. There is one acceleration vector linking each set of two velocity vectors. Each acceleration vector is drawn at the dot between the two velocity vectors it links. Use to indicate a point at which the acceleration is zero. Label the row of acceleration vectors . Model It is appropriate to use the particle model for the car. You should also make some simplifying assumptions. v 0 a Part A The car’s motion can be divided into three different stages: its motion before the driver realizes he’s late, its motion after the driver hits the gas (but before he sees the police car), and its motion after the driver sees the police car. Which of the following simplifying assumptions is it reasonable to make in this problem? During each of the three different stages of its motion, the car is moving with constant A. acceleration. B. During each of the three different stages of its motion, the car is moving with constant velocity. C. The highway is straight (i.e., there are no curves). D. The highway is level (i.e., there are no hills or valleys). Enter all the correct answers in alphabetical order without commas. For example, if statements C and D are correct, enter CD. ANSWER: Correct In addition to the assumptions listed above, in the rest of this problem assume that the car is moving in a straight line to the right.

A B C cm ANSWER: Correct If you’re not familiar with metric units of length, you can use your body to develop intuition for them. The average height of an adult is 5 6.4 . The distance from elbow to fingertips on the average adult is about 50 . Ten (1 ) is about the width of this adult’s little finger and 10 is about the width of the average hand. Part B Approximately what is the mass of the average adult in kilograms? Hint 1. Converting between pounds and kilograms Something that weighs 1 has a mass of about . ANSWER: Correct Something that weighs 1 has a mass of about . This is a useful conversion to keep in mind! ± A Trip to Europe 100 200 300 cm cm cm feet inches cm mm cm cm pound 1 kg 2 80 500 1200 kg kg kg pound (1/2) kg Learning Goal: To understand how to use dimensional analysis to solve problems. Dimensional analysis is a useful tool for solving problems that involve unit conversions. Since unit conversion is not limited to physics problems but is part of our everyday life, correct use of conversion factors is essential to working through problems of practical importance. For example, dimensional analysis could be used in problems involving currency exchange. Say you want to calculate how many euros you get if you exchange 3600 ( ), given the exchange rate , that is, 1 to 1.20 . Begin by writing down the starting value, 3600 . This can also be written as a fraction: . Next, convert dollars to euros. This conversion involves multiplying by a simple conversion factor derived from the exchange rate: . Note that the “dollar” unit, , should appear on the bottom of this conversion factor, since appears on the top of the starting value. Finally, since dollars are divided by dollars, the units can be canceled and the final result is . Currency exchange is only one example of many practical situations where dimensional analysis may help you to work through problems. Remember that dimensional analysis involves multiplying a given value by a conversion factor, resulting in a value in the new units. The conversion factor can be the ratio of any two quantities, as long as the ratio is equal to one. You and your friends are organizing a trip to Europe. Your plan is to rent a car and drive through the major European capitals. By consulting a map you estimate that you will cover a total distance of 5000 . Consider the euro-dollar exchange rate given in the introduction and use dimensional analysis to work through these simple problems.

COMM 1311: Written Communication Assignment 5 Argumentation Essay (Chapter 10, pp. 218-232, Arlov) Purpose of Assignment • The purpose of this assignment is to enable the student to write an essay with a compelling argumentation that shows critical thinking. A persuasive essay is a writer’s attempt to convince readers of the validity of a particular opinion on a controversial issue. Objectives • The student will be able to correctly structure an essay and bring forward a compelling thesis and argument. • The student will understand the creativity of the writing process and use his own ideas. • The student will be able to craft a compelling essay and show critical thinking. • The student will show that he is able to argue both sides of a topic and is willing to acknowledge a different opinion. Instructions 1. Establish a subject Choose a topic that interests you. An argument does not have to be a burning issue, but it must be a debatable topic. It can be anything you feel strongly about but it has to be approved by the instructor. 2. Present a clear thesis and identify the controversy Your thesis should inform readers of your purpose and how you will proceed in your argumentation. 3. Follow an organizational pattern and provide support The body paragraphs of the essay should provide specific support. These supports may include personal experience, statistics, facts, or experts’ opinions. They may be garnered from scientific journals, magazines, books, newspapers, textbooks, studies, or interviews. Select only the facts that are relevant. 4. Consider differing opinions A persuasive essay may be strengthened by acknowledging conflict viewpoints and discussing them. 4. Draw a conclusion Restate your position in different words from the introduction. Do not introduce new material in the conclusion. You may want to conclude by encouraging some specific call to action. Requirements The essay topic must meet the approval of the instructor: • Have a complete cover page • have at least 500 words • use full sentences (and no bullet points) • must have page numbers • must have a reference page Example writing (not a complete essay): Boxing: Countdown to Injury A left hook smashes into the fighter’s jaw. A following right slams his head the opposite direction. An uppercut to the jaw snaps his head back, momentarily stopping the blood flow to his brain. The boxer drops, hitting the mat with a thud. His brain bounces off his skull for the second time in a matter of seconds. Is this what we should call a sport? Because of injuries, neurological damage, and ring deaths, the rules of professional boxing should be changed. Boxing has always been a brutal sport. The ancient Greeks used gloves studded with metal spikes, which slashed the face and body and split skulls. Although gloves are no longer spiked, boxers today sustain injuries ranging from cuts and bruises to broken bones. It is not uncommon to see a boxer leave the ring with a cut on his face, an eye swollen shut, and a nose enlarged and bloody. Often, healing in is incomplete because these areas receive the same blows again and again in other matches. In fact, repeated blows almost cost Sugar Ray Leonard his sight when his retina detached in his left eye. Besides superficial injuries, boxers suffer short-term neurological damage as a result of staggering blows to the head. A knockout punch, for example, is often delivered with such force that the brain smashes against the skull, tearing nerve fibers and blood vessels, resulting in a concussion. Even a blow to the neck can close the carotid artery, the main artery to the brain, whereby oxygen and blood to the brain are disrupted, resulting in dizziness and confusion. Later, the boxers often have no memory of the moments before or after a knockout blow. Submission Criteria Due Date: Sunday, December 6, 2015. Late assignments will receive an automatic ZERO grade. Where to deliver hard copies: In class Assessment Criteria CRITERIA Assessment Rubric Argumentation Essay SCORES Introduction Introduces the issue and its importance, says what your essay will cover 2 Organization The sound structure of the essay 1 Expression Sentences, phrases, metaphors, verbs etc. The strength of the language used 4 Conclusion Restate the issue, summarizes the strength of the arguments in the essays, gives your opinion about which essay is the strongest with supporting reasons 1 Mechanics Followed guidelines, professional format, punctuation, spelling, and capitalization are correct, use of headings, no bullet points 2 TOTAL 10% Plagiarism, copying from the internet or any other sources without citation will result in an automatic ZERO grade and a procedure of Academic Misconduct will filed against you. The complete essay has to be created and written by you alone. Prior assignments CAN NOT be used.

Paper 1: Summary Our first few weeks of class have been devoted to summaries, and the practice of writing effective, informative synopses of longer texts. In each class session, we have discussed how to read an article or essay to extract its major points, how to phrase those points in your own words, how to organize those points logically, and how to ensure that your summary accurately reflects the contents of the original text. We have also focused on the importance of summaries for academic work, as they allow readers to understand the key elements of a significant issue or phenomenon, and allow writers to test their knowledge of a text by explaining its main points in brief. For this assignment, you will write a summary of either Lee Ross and Richard E. Nisbett’s “The Power of Situations” (WRAC, 579-582) or Solomon E. Asch’s “Opinions and Social Pressure” Your summary should clearly restate the central claim or thesis of the essay you select, go through the essay’s subordinate claims that support that thesis, and provide a few brief examples that illustrate those claims. Remember that you are not to offer your opinion on the essay – rather, you are summarizing the contents of the essay, without making your own arguments about those contents. Things to Keep in Mind When writing your summary, ask yourself the following questions: • Does this summary begin by stating the thesis of the essay you’ve chosen? • Does that statement of the thesis clearly communicate the central argument of the entire essay? That is, does it give the reader a firm sense of what the whole essay is about? • Are the subordinate points you’ve provided the most significant points within the essay that support the essay’s thesis? • Are the examples you’ve chosen important to understanding the essay’s argument? • Is the summary organized logically, with each idea clearly building upon its predecessor? • Is the summary clearly written, and free of grammatical errors? These will be the questions I ask as I evaluate your summary, so keep them in mind as you’re writing. You should also look over them again once you’ve finished the summary, and make any revisions you might need before submitting the final summary for a grade. Formal Requirements Papers should be 2-3 full pages long (no less, and not significantly more), typed in 12-point, Times New Roman font, and double-spaced. All papers must include a list of works cited, and all in-text citations should be provided in MLA format.
