(i)[2]
Find the displacement of $P$ from $O$ when $t = 10$.
(ii)[5]
Given that $Q$ has the same velocity as $P$ when $t = 10$, show that it also has the same displacement from $O$ as $P$ when $t = 10$.

Kinematics of motion in a straight line — practice question
A particle $P$ leaves a fixed point $O$ at $t = 0$, where $t$ is measured in seconds, and travels in a straight line with constant acceleration. Its initial velocity is $1.5\,\text{m s}^{-1}$ and its velocity at $t = 10$ is $3.5\,\text{m s}^{-1}$.
