The mass of a regulation tennis ball is 57.0g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30.0ms . (This number can also vary, depending on the racket and swing.) We shall assume a 30.0ms contact time throughout this problem. The fastest-known served tennis ball was served by “Big Bill” Tilden in 1931, and its speed was measured to be 73.14 m/s. If Big Bill’s opponent returned his serve with a speed of 55.0m/s , what is the magnitude of the force that he exerted on the ball, assuming only horizontal motion? If Big Bill’s opponent returned his serve with a speed of 55.0m/s , what is the magnitude of the impulse that he exerted on the ball, assuming only horizontal motion?
