(i)[3]
Calculate the time taken by the ball to move from $O$ to $P$ and the distance $OP$.
(ii)[4]
Since the horizontal component of the ball's velocity does not alter at $P$, calculate the speed of the ball as it leaves $P$.

A ball is launched with velocity $25\,\text{m s}^{-1}$ at an angle of $70^{\circ}$ above the horizontal from a point $O$ on level ground. It then rebounds once on the ground at a point $P$ before coming to rest at a point $Q$. The distance $PQ$ is $17.1\,\text{m}$.
