The mass of a regulation tennis ball is 57.0 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30.0 ms . (This number can also vary, depending on the racket and swing.) We shall assume a 30.0 ms 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.
Part A)What impulse did Big Bill exert on the tennis ball in his record serve?
Part B)What force did Big Bill exert on the tennis ball in his record serve?
Part C)If Big Bill's opponent returned his serve with a speed of 55.0 m/s , what is the magnitude of the force that he exerted on the ball, assuming only horizontal motion?
Part D)If Big Bill's opponent returned his serve with a speed of 55.0 m/s , what is the magnitude of the impulse that he exerted on the ball, assuming only horizontal motion?

Please answer all four Re - Part A The mass of a regulation tennis ball is 57 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30 m. (This number can also vary, depending on the racket and swing.) We shall assume a 30.0-ius contact time. The fastest- known served tennis ball was served by "Big Bill' Tilden in 1931, and its speed was measured to be 73...
Constants Part A In the fastest measured tennis serve, the ball left the racquet at 73.14 m/s. A served tennis ball is typically in contact with the racquet for 27.0 ms and starts from rest. The direction of the velocity of the ball just after it left the racquet is the positive direction. Assume constant acceleration What was the r component of the ball's acceleration during this serve? ay Submit Part B How far did the ball travel during the...
a) On a throw-in, a tennis player hits his 0.075 Kg ball with the racket, providing him with an impulsive force. Assuming that the ball and the racket are in contact for 5 ms and then the ball leaves the racket at a speed of 40 m / s, what would be approximately the average racket force on the ball? Ignore all other forces, including gravity b) Water flows out of a hose at a rate of 1.2 Kg for...
