Express your answer to two significant figures and include the appropriate units. ANSWER: Correct to the right to the left Fmax Ns Fmax = 1.6×103 N Typesetting math: 100% Impulse on a Baseball Learning Goal: To understand the relationship between force, impulse, and momentum. The effect of a net force acting on an object is related both to the force and to the total time the force acts on the object. The physical quantity impulse is a measure of both these effects. For a constant net force, the impulse is given by . The impulse is a vector pointing in the same direction as the force vector. The units of are or . Recall that when a net force acts on an object, the object will accelerate, causing a change in its velocity. Hence the object’s momentum ( ) will also change. The impulse-momentum theorem describes the effect that an impulse has on an object’s motion: . So the change in momentum of an object equals the net impulse, that is, the net force multiplied by the time over which the force acts. A given change in momentum can result from a large force over a short time or a smaller force over a longer time. In Parts A, B, C consider the following situation. In a baseball game the batter swings and gets a good solid hit. His swing applies a force of 12,000 to the ball for a time of . Part A Assuming that this force is constant, what is the magnitude of the impulse on the ball? Enter your answer numerically in newton seconds using two significant figures. ANSWER: Correct We often visualize the impulse by drawing a graph of force versus time. For a constant net force such as that used in the previous part, the graph will look like the one shown in the figure. (F J J = F) t J N * s kg * m/s p = mv )p = J = F) t N 0.70 × 10−3 s J J = 8.4 N * s Typesetting math: 100% Part B The net force versus time graph has a rectangular shape. Often in physics geometric properties of graphs have physical meaning. ANSWER: Correct The assumption of a constant net force is idealized to make the problem easier to solve. A real force, especially in a case like the one presented in Parts A and B, where a large force is applied for a short time, is not likely to be constant. A more realistic graph of the force that the swinging bat applies to the baseball will show the force building up to a maximum value as the bat comes into full contact with the ball. Then as the ball loses contact with the bat, the graph will show the force decaying to zero. It will look like the graph in the figure. For this graph, the length height area slope of the rectangle corresponds to the impulse. Typesetting math: 100% Part C If both the graph representing the constant net force and the graph representing the variable net force represent the same impulse acting on the baseball, which geometric properties must the two graphs have in common? ANSWER: maximum force area slope Typesetting math: 100% Correct When the net force varies over time, as in the case of the real net force acting on the baseball, you can simplify the problem by finding the average net force acting on the baseball during time . This average net force is treated as a constant force that acts on the ball for time . The impulse on the ball can then be found as . Graphically, this method states that the impulse of the baseball can be represented by either the area under the net force versus time curve or the area under the average net force versus time curve. These areas are represented in the figure as the areas shaded in red and blue respectively. The impulse of an object is also related to its change in momentum. Once the impulse is known, it can be used to find the change in momentum, or if either the initial or final momentum is known, the other momentum can be found. Keep in mind that . Because both impulse and momentum are vectors, it is essential to account for the direction of each vector, even in a one-dimensional problem. Part D Assume that a pitcher throws a baseball so that it travels in a straight line parallel to the ground. The batter then hits the ball so it goes directly back to the pitcher along the same straight line. Define the direction the pitcher originally throws the ball as the +x direction. ANSWER: F avg )t )t J = F )t avg J = )p = m(vf − vi ) Typesetting math: 100% Correct Part E Now assume that the pitcher in Part D throws a 0.145- baseball parallel to the ground with a speed of 32 in the +x direction. The batter then hits the ball so it goes directly back to the pitcher along the same straight line. What is the ball’s velocity just after leaving the bat if the bat applies an impulse of to the baseball? Enter your answer numerically in meters per second using two significant figures. ANSWER: Correct The negative sign in the answer indicates that after the bat hits the ball, the ball travels in the opposite direction to that defined to be positive. Problem 9.9 A 2.6 object is moving to the right with a speed of 1.0 when it experiences the force shown in the figure. The impulse on the ball caused by the bat will be in the positive negative x direction. kg m/s −8.4 N * s v = -26 m/s kg m/s Typesetting math: 100% Part A What is the object’s speed after the force ends? Express your answer to two significant figures and include the appropriate units. ANSWER: Correct Part B What is the object’s direction after the force ends? ANSWER: Correct Enhanced EOC: Problem 9.27 A tennis player swings her 1000 g racket with a speed of 11.0 . She hits a 60 g tennis ball that was approaching her at a speed of 19.0 .

Genetics contribute to our risk of developing certain diseases and disorders. Researchers have found a genetic influence in many common disorders including heart disease, diabetes, depression, asthma, alcoholism, and certain forms of cancer. Knowing that a specific disease runs in your family allows you to watch for early warning signs and get screening tests more often than you otherwise would. Looking at your family health history can help you make important decisions about behaviors such as diet, maintaining a healthy weight, moderate alcohol consumption, and keeping physically active. For example, an individual with a family health history of high cholesterol and early heart disease can increase physical activity and pay special attention to certain aspects of their diet. Generally, the more relatives with a genetically linked disease and the closer they are related to you, the greater your risk of having the disease. Keep this in mind when choosing your research paper topic. If you do not use proper documentation (MLA or APA format look these up if you do not know what to do!) you will lose 25 points. Grading criteria is given below. Follow the steps below to help you complete the requirements for your research paper. 1. The content of your paper should include the following information about the disease, disorder, healthrelated condition or habit. Description Cause(s) Treatment Prevention Effect(s) of diet Effect(s) of activity/exercise 1. Use a minimum of five reliable sources. It is NEVER enough to simply put a URL or web link as a source on a Works Cited page. You must include titles of articles, names of authors and websites, dates of publication and/or dates you retrieved information, etc. Books Professional journals Personal interviews Reputable Internet sites Research articles ***See “Web Sites: Tips for Finding Reliable Health Information” at the bottom of this document. 3. You must document your research. Parenthetical citations must be used throughout your paper. You should put into your own words the information you learn from your research. Then, you must document from whom and where you found the information. This is done, for APA format, by putting the author’s name at the end of a sentence or paragraph with the date of the published information and enclosing it in parentheses. An example of this would be as follows: The six classes of nutrients are carbohydrates, lipids, proteins, vitamins, minerals and water (Wardlaw, 2010). I found the information in our textbook and used it in my research paper. I must give Wardlaw credit for the information and tell the reader where they can find the information. 4. Write your paper in MLA or APA format. If you are not familiar with either of these writing styles, you can go online to a search engine like Google or www.ask.com (http://www.ask.com/) and type in either MLA or APA format. This will give you several documents that will help you with proper documentation and format and will give you some examples. 5.
