Use the figure to answer the problem. A spring of negligible mass and spring constant k is attached to the wall on one end, and the other end is attached to the center of mass axis of a solid sphere of mass m and radius r. The spring is stretched a distance A from equilibrium and let go. The sphere rolls freely on a smooth surface.
-What is the rotational kinetic energy when the sphere is at the equilibrium position?
E) undetermined
