You throw a 0.350 kg tennis ball horizontally toward a wall. The speed of the ball is 12 m/s before it hits the wall, and it bounces back with the same speed of 12 m/s. If the ball remains in contact with the wall during this collision for 0.025 s, what is the magnitude of the average force exerted on the ball?

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...
