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 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 0.5 kg moving with a velocity of 2 m//s strikes a wall normally and bounces back with the same speed . If the time of contact between the ball and the wall is 1 millisecond , the average force exerted by the wall on the ball is

A ball of mass 0.5 kg moving with a velocity of 2 m//s strikes a wall normally and bounces back with the same speed . If the time of contact between the ball and the wall is 1 millisecond , the average force exerted by the wall on the ball is

A ball of mass 0.5 kg moving with a velocity of 2 m//s strikes a wall normally and bounces back with the same speed . If the time of contact between the ball and the wall is 1 millisecond , the average force exerted by the wall on the ball is

A ball of mass 3kg moving with a speed of 100 m/s, strikes a wall at an angle 60^(@) (as shown in figure). The ball rebounds at the same speed and remains in contact with the wall for 0.2 s, the force exerted by the ball on the wall is
