A ball of mass 250 g moving with 20 m/s strikes a vertical wall and rebounds along the same line with a velocity of 15 m/s. If the time of contact is 0.1 s, the force exerted by the wall on the ball is

A ball of mass 500 gram strikes a wall with a velocity of 80 m/s and rebounds with the same velocity. If the tme of contact is 1/30 sec, then the force exerted by the ball on the wall is

A ball of mass 2 kg is moving with velocity 20 m/sec strikes with the surface and rebounds with same speed, if time of contact is 0.1 sec then calculate average force on the ball.

A ball of mass 2 kg is moving with velocity 20 m/sec strikes with the surface and rebounds with same speed, if time of contact is 0.1 sec then calculate average force on the ball.

A ball of mass 2 kg is moving with velocity 20 m/sec strikes with the surface and rebounds with same speed, if time of contact is 0.1 sec then calculate average force on the ball.

A cricket ball of mass 0.5 kg, moving at 30 m cdot s^(-1) , hits a bat perpendicularly and rebounces with a velocity of 20 m cdot s^(-1) . Impulse of the force exerted by the ball on the bat is

A ball of mass 10 gm dropped from a height of 5m hits the floor and rebounds to a height of 1.25m. If the ball is in contact with the ground for 0.1s, the force exerted by the ground on the ball is (g=10 m//s^(2))
