... Ex 7-1 Force of a tennis serve For a top player, a tennis ball may leave the racket on the serve with a speed of 55 m/s (about 120 mph). If the ball has a mass of 0.060 kg and is in contact with the racket for about 4 ms (4x10-3 s), estimate the average force on the ball. Would this force be large ...
