A ball with radius R and I = (2/5)mR2 is thrown through the air. It spins around the axis perpendicular to the plane of the motion (call this the x- y plane). The ball bounces off a floor without slipping during the time of contact. Assume that the collision is elastic, and that the magnitude of the vertical vy is the same before and after the bounce. Show that vx and ? after the bounce are related to vx and ? before the bounce by

where positive vx is to the right, and positive ? is counterclockwise.
