A ball hits a wall horizontally at 6.0 m s^(-1) . It rebounds horzontally at 4.4 m s^(-1) . The ball is in contact with the wall for 0.040 s. What is the acceleration of the ball ?

A ball hits a vertical wall horizontal at 10 m/s bounces back at 10 m/s

A ball hits a vertical wall horizontal at 10 m/s bounces back at 10 m/s

A steel ball of mass 0.5 kg is dropped from a height of 4 m on to a horizontal heavy steel slab. The collision is elastic and the ball rebounds to its original height. If the ball is in contact with the slab for 0.002 s, find the average reaction force on the ball during impact.

A ball is dropped on the floor a height of 80 m rebounds to a height of 20 m . If the ball is in contact with floor for 0.1 s, the average acceleration during contact is

A "150 g" ball, moving horizontally at "20 m/s" was hit straight back to bowler at "35 m/s" . If contact with bat lasted for 0.04 sec , than average force exerted by the bat 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

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

A ball weighing 10g hits a hard surface vertically with a speed of 5m/s and rebounds with the same speed. The ball remains in contact with the surface for 0.01s. The average force exerted by the surface on the ball is
