Distance and Displacement

The displacement $x$ of particle moving in one dimension, under the action of a constant force is related to the time $t$ by the equation $t=\sqrt{x}+3$ where $x$ is in meters and $t$ in seconds. Find the displacement of the particle when its velocity is zero.

A particle moves in a circle of radius $R.$ Find its displacement and the distance covered for half the period of its revolution.
