A ball hits a wall horizontally at 6.0 m/s-1. It rebounds horizontally 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?

Answer :

According to the Question:-

Initial velocity, u=6m/s

Final velocity ,v=(-4.4m/s) (the ball rebounds in opposite direction)

Time, t = 0.040 s
 
We know that v= u+at
