b. In Case A, a ball is released from rest at the top of a frictionless hill of height h. In Case B, an identical ball is released from rest at the top of a hill of height h with sufficient friction that the ball can roll without slipping. In which case does the center of mass of the ball have a larger speed at the bottom of the hill or is it the same in both cases? Explain.
