A super-ball of mass m is to bounce elastically back and forth between two rigid walls at a distance d from each other. Neglecting gravity and assuming the velocity of super-ball to be `v_(0)` horizontally, the average force being exerted by the super-ball on each wall 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 heavy block A is made to move uniformly along a smooth floor with velocity V = 0.01 m/s towards left. A ball of mass m = 50 g is projected towards the block with a velocity of u = 100 m/s. The ball keeps bouncing back and forth between the block A and fixed wall B. Each of the collisions is elastic. After the ball has made 1000 collisions with the block and wall each, the distance between the block and the wall was found to be L = 1.2 m . Calculate the average force being experienced by the block due to collision at this instant. All collision are instantaneous
