Question

A ball hits a wall horizontally at 6.0 m/s it rebounds horizontally at4.4m/s the ball is in contact with the wall for 0.040s what is the acceleration of the ball the acceleration is 0.4 prove it

Answer 1

Explanation:

Initial velocity, u = 6 m/s

Final velocity, v = 4.4 m/s

Time taken, t = 0.040 s

a = v - u / t

a = 4.4 - 6 /0.04

a = -1.6 / 0.04

a = -40 m/s

Thus, the acceleration is -40 m/s
