If the displacement of an object is proportional to square of time, then the object moves with

A

uniform velocity

B

uniform acceleration

C

increasing acceleration

D

decreasing acceleration

Text Solution

Verified by Experts

The correct Answer is:
B
From `s = ut + (1)/(2)at^(2)`, `s = (1)/(2)at^(2)`, when `u = 0`.
If a is constant, `s prop t^(2)`
i.e., when acceleration is uniform, `s prop t^(2)`.
