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?
