Question

A particle moves in a straight line, so that x =√t
Then its acceleration is proportional to
(1) Velocity
(2) (Velocity)3/2
(3) (Velocity)³
(4) (Velocity)2​

Answer 1

Acceleration is proportional to velocity ³

by differenciating the eq given for x u can find a and v

then compare their equations

Answer 2

Answer:

I think (2) Option is correct
