# Question #e4198

##### 1 Answer

We know that the conservative force

Here it is given that

So

So acceleration

where

Hence

When the body crosses the Y-axis, then x=0.

Again it is given that body is at **rest** at the position (6m,4m) at t=0

This means

at x=6m, velocity =0;

When the body crosses Y-axis,its displacement along X-axis becomes

If this displacement occurs in t sec due to its movement with acceleration along X axis

then we can write
