hence velocity = acceleration *time
i. e. v=a*t
The answer to the question is
CALCULATION:
As per the question, the body starts from rest.
Hence, initial velocity of the body u = 0.
The acceleration of the body is given as a .
The time taken by the body is given as t.
Let the distance covered by the body in time t is S.
From equation of kinematics, we know that-
⇒
⇒
The average velocity of a body is defined as the ratio of total distance travelled to total time taken.
