Question

A body starts from origin and moves along x axis so that its position at any instant is x =4t-12t where t is in second amd v in m/s. What's is the acceleration of particle?

Answer 1

Hi friend,

Given equation for displacement
X= 4t-12 t

By first time differentiating it becomes velocity

X= 4-12

X=-8

By second time differentiating it becomes acceleration.

Hence on differentiation it becomes zero.

So acceleration = zero.

Hope this helped you a little!!!!
