Kinematics of motion in a straight line — practice question

A particle $P$ moves from point $O$ in a straight line and reaches instantaneous rest at point $A$. The velocity of $P$ after time $t$ since leaving $O$ is $v\,\text{m s}^{-1}$, where $v = 0.027(10t^2 - t^3)$.
(i)[4]

Find the length of $OA$.

(ii)[3]

Find the maximum velocity of $P$ as it travels from $O$ to $A$.
