Question

A ball hits a wall harizontally at 6,0m/s it renounces horizontally at 4.4m/s the ball is in contact with the wall for 0.040 s what is the accelaration

Answer 1

Answer:

65m/s2

Explanation:

given

initial velocity = 6m/s

final velocity = 4.4m/s

time = 0.040 s

acceleration = initial velocity - final velocity / time

acceleration = 6-4.4/0.040

acceleration = 2.6/0.040

acceleration = 65
