A car increases its velocity from 7.8 m/s to 11.4 m/s with constant the average acceleration, the average velocity of the car would be 9.6 m/s
The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
As given in the problem a car increases its velocity from 7.8 m/s to 11.4 m/s with constant the average acceleration,
average velocity = maximum velocity + minimum velocity /2
average velocity = (7.8 + 11.4)/2
= 9.6 m/s
Thus, the average velocity of the car would be 9.6 m/s
