Unformatted text preview: Ch8_3 Due: 10:00pm on Friday, October 22, 2010 Note: You will receive no credit for late submissions. To learn more, read your instructor's Grading Policy [ Switch to Standard Assignment View] You should make a serious attempt at these problems before your October 22 workshop. You only have a couple of hours after the work shop to make final adjustments before the due time !! You will do poorly in the work shop if you are unprepared. !! If you need help consult the Help Blog and/or visit the help room. Rotational Kinetic Energy and Conservation of Energy Ranking Task The five objects of various masses, each denoted , all have the same radius. They are all rolling at the same speed as they approach a curved incline. Part A Rank the objects based on the maximum height they reach along the curved incline. Hint A.1 Using energy conservation As the objects roll up the incline, their initial kinetic and rotational kinetic energy gets converted into gravitational potential energy. Both kinetic and rotational kinetic energy are directly proportional to mass. Thus, objects with large mass will have proportionally more energy than objects with low mass. The same is true for gravitational potential energy.directly proportional to mass....
