Find the ratio of height h of a cushion on a snooker table to the radius r of a ball as shown in the figure, such that when the ball hits the cushion with a pure rolling motion it rebounds with a pure rolling motion. (Assume that the force exerted on the ball by the cushion is horizontal during the impact and that the ball hits the cushion normally)
