A ball of mass 1 kg moving with a speed of `10 ms^(-1)` rebounds after a pefect elastic collision with the floor. Calculate the change in linear momentum of the ball.

A ball of mass 0.5kg moving with a speed of 10m//s rebounds after striking normally a perfectly elastic wall. Find the change in momentum of the ball . If contact time with the wall is 0.1s , what force is exerted by wall?

A ball of 0.5 kg mass moving with a speed of 10 m//s rebounds after strinking normally a perfectly elastic wall . Find the change in momentum of the ball.

When a ball of 0.5 kg mass moving with a speed of 20 ms^(-1) rebounds after striking normally a ferfectly elastic wall. Find the change in momentum.

A ball of 4 kg mass moving with a speed of 3ms^(-1) has a head on elastic collision with a 6 kg mass initially at rest. The speeds of both the bodies after collision are respectively

A ball hits the floor and rebounds after an inelastic collision. In this case
