In a case of a motion, displacement is directly proportional to the square of the time elapsed. What do you think about its acceleration i.e., constant or varianle ? Explain why ?

Explanation

Goven ` x prop t^(2) or x =kt^(2)` where (k) is a constant
Velocity, ` v =(dx)/(dt) = 2 k =a` canstant
Hence, the acceleration of moting object is constant.
