Question

A particle is moving in straight line such that it's instantaneous displacement is cube of the time elapsed. Comment in acceleration.

Answer 1

given,

x=t³

differentiating with respect to 't' we get


v=3t²

where v is the velocity


again differentiating with respect to t ,we get

a=6t

so the acceralation is 6 times the time elapsed


I hope this will help u :)
