The distance travelled by a particle is proportional to the squares of time, then the particle travels with

A

Uniform acceleration

B

Uniform velocity

C

Increasing acceleration

D

Decreasing velocity

Solution

(a) $s \propto {t^2}$ (given)

$\therefore s = K{t^2}$

Acceleration $a = \frac{{{d^s}s}}{{d{t^2}}} = 2k$ (constant)
It means the particle travels with uniform acceleration.
