Phys 100 Fall 2011 Concepts of Physics: Homework 5 Due: 5 October 2011 In order to receive full credit, you must show all work, calculations and provide complete reasons and explanations for your solutions. 1 Hobson, Physics: Concepts and Connections, 5ed Ch. 6, Review Question 12, page 132. State your response as precisely as possible, e.g. if you think the energy decreases/increases, state by how many times (or what factor) it decreases/increases. 2 Hobson, Physics: Concepts and Connections, 5ed Ch. 6 Problem 10, page 135. Assume that the runner has mass 60 kg . The idea here is to determine how many times larger the energy while running is than while jogging. 3 Energy and a skater Running the Animation: The following exercise will require the animation “Energy Skate Park” provided by the PhET group. There will generally be two parts to this: 1. Running the animation 2. Loading specially designed tracks. The animation can be accessed at one of the following locations: http://phet.colorado.edu/sims/energy-skate-park/energy-skate-park.jnlp http://myhome.coloradomesa.edu/ dacollin/teaching/2011Fall/Phys100/animations/skater.jar Click on the link and, at the Java prompt, open the animation. A track should appear. A skater will move on this track. There are a number of adjustable controls in the panel on the right. Ensure that the location is “Earth” and that the gravity is 9 . 81 . There should be no friction. The panel at the bottom controls the speed of the animation and you can freeze it

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
