The displacement of a particle moving in one dimension under the action of a constant force is

The displacement of a particle moving in one dimension under the action of a constant force is related to the time t by the equation t = square root of x + 3, where x is in metre and t is in second. Find the displacement of the particle when its velocity is zero

The velocity can not be zero if the force is being exerted and there is some displacement due to force, so the answer is that velocity can’t be zero
