A small ball is projected from point A on the floor towards a vertical wall as shown in the figure. It hits the wall when its velocity is horizontal. Ball reaches point A after one bounce on the floor. If the coefficient of restitution is the same for the collisions, find its value

A ball of 0.2 kg hits a wall with a velocity of 25 m/s at an angle of 45°. If the ball rebounds at 90° to the direction of incidence, change in momentum of the ball -

A ball of mass 0.5 kg hits a vertical wall at a speed of 12 m s –1. It bounces back along its originalpath with a speed of 8 m s –1. The collision lasts for 0.10 s.12 m s–18 m s–1What is the average force on the ball due to the collision?A 0.2 N B 1 N C 20 N D 100 N

A tennis ball of mass 50g is hit against a wall. It hits the wall going right at 5 ms-1 and rebounds to the left at 4 ms-1, changing its momentum by 0.45 kg m/s left. The ball is in contact with the wall for 0.2 s and experiences an average force of 2.25 N left (applied by the wall).What is the force of the ball on the wall?
