TA: Tomoyuki Nakayama Wednesday, March 16, 2011 PHY 2048: Physic 1, Discussion Section 1243H Quiz 6 (Homework Set #8) Name: UFID: Formula sheets are not allowed. Do not store equations in your calculator. You have to solve problems on your own; memorizing final algebraic expressions from homework assignments and just plugging numbers into them will not give you full credit. Leave all your work. ________________________________________________________________________________ The figure below shows the potential energy U(x) of a hollow sphere that can roll along an x axis. The scale of the vertical axis is set by U s = 500 J. The sphere rolls smoothly, and has a mass of 2.00 kg. The rotational inertia of the hollow sphere is I = (2/3)mr 2 . It is released at x = 6.0 m headed in the negative direction of the x axis with a mechanical energy of 450 J. a) If the ball can reach x = 0 m, what is its speed there, and if it cannot, what is its turning point? While the ball rolls along the x axis, the
