Explanation:
Let s is the displacement of the body. The formula that relates the acceleration, displacement and the velocity is given by :
The body is at rest initially, u = 0. Put t = 2 sec in above formula as :
So, when a body starts from rest, the acceleration of the body after 2 seconds is half of its displacement. Hence, this is the required solution.
