Experimental Coefficient of Friction for the Impact of a Tennis Ball

The impact of a tennis ball with a surface has been mostly studied for the normal impact. Garwin [1] and Brody [2] have studied the physics of the oblique impact. Brody [2] studied the oblique impact of a tennis ball on tennis courts. He used Newtonian mechanics with the assumption of constant coefficient of restitution, and the tennis ball was considered rigid. However, it has been shown that the coefficient of restitution reduces with the increase of the initial velocity for the impacts with a rigid surface, [3, 4, 5].
