A ball reaches a racket at `60m//s` along +X dirction and leaves the racket in the opposite direaction with the same speed. Assuming that the mass of the ball as `50gm` and the contact time is `0.02` second the force exerted by the racket on the ball is .

A ball weighing 10 gm hits a hard surface vertically with a speed of 5 m//s and rebounds with the same speed. The ball remains in contact with the surface for 0.01 sec. The average force exerted by the surface on the ball is :

The tennis ball may leave the racket of a top player on the serve with a speed of 65 m/s If mass of the ball is 0.06 kg and is in bontact with the racket for 0.03 sec, what the average force n the ball ?

A ball weighing 50g hits a hard surface normally with a speed of 25m/s and rebounds with the same speed. The ball remains in contact with the surface for 0.05s .The average force exerted by the surface on the ball is?

A ball weighing 10g hits a hard surface vertically with a speed of 5m/s and rebounds with the same speed. The ball remains in contact with the surface for 0.01s. The average force exerted by the surface on the ball is

A 3-kg steel ball strikes a wall with a speed of 10.0ms^(-1) at an angle of 60.0^(@) with the surfaces of the wall. The ball bounces off with the same speed and same angle. If the ball was in contact with the wall for 0.2s, find the average force exerted by the wall on the ball.
