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 $A$.
Worked solution & mark scheme
This 7-mark question has a full step-by-step worked solution and mark scheme. One marking point: “Use $s = \int v\,dt$ to relate displacement and velocity.” …
