A ball hits a wall horizontally at 6 m/s. It rebounds horizontally at 4.4m/s. The ball is in contact with the wall for 0.04 s. What is the acceleration of the ball?

The acceleration of the ball is -260 m/s². It is opposite to the initial facility which will help in retardation to slow the ball down. Steps to calculate the acceleration of the ball.

Now we have to assume that the ball is moving in a forward direction then,

● Initial velocity u = 6 m/s

● Time was taken during change of velocity = 0.04 s

● Final velocity v = 4.4 m/s = -4.4 m/s

We know that:

Acceleration = (v-u)/t = change in velocity/time

In simplification we get the:

a = ( -4.4 -6)/ 0.04

= -10.4/0.04

= -1040/4

In simplification we get the:

a = -260 m/s²

The acceleration of the ball is -260 m/s². Since it is moving against the original velocity, it will retard the ball and cause it to go more slowly.

If an object's velocity changes, it is said to have been accelerated. An object's velocity can alter depending on whether it moves faster or slower or in a different direction. A falling apple, the moon orbiting the Earth, and a car stopped at a stop sign are a few instances of acceleration.

Summary:

A ball hits a wall horizontally at 6 m/s. It rebounds horizontally at 4.4m/s. The ball is in contact with the wall for 0.04 s. What is the acceleration of the ball?
