#### Question

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 ?

#### Solution

We have to find the value of uniform acceleration.

We have:

Initial velocity (u) = 6 m/s

Final velocity is in opposite direction to that of initial velocity (v) = –4.4 m/s

Time taken (t) = 0.04 s

Acceleration :

`a = "υ-u"/t`

Put the values in the above equation to get the value of acceleration .

`a = "-4.4-6"/0.04`

= `10.4/0.04`

= `-260 "m/s"^2`

Is there an error in this question or solution?
