Question

A vehicle increases its speed from 50 m/s to 75 m/s.Calculate its acceleration.

Answer 1

Explanation:

Falling object is influence by acceleration due to gravity which is 9.8 m/s². This means that in every one second the change in velocity is 9.8 m/s and the velocity increases by 9.8 m/s every second. So after one second, the acceleration of the ball is 9.8 m/s² and its velocity is 9.8 m/s.
