| Topic | Variable acceleration (1D) |
| Type | Displacement from velocity by integration |
| Difficulty | Moderate -0.8 This is a straightforward kinematics problem using standard SUVAT equations with constant acceleration due to gravity. Students need to apply s = ut + ½at² for part (a) and v = u + at for part (b), both routine M1 techniques requiring minimal problem-solving beyond identifying the correct equations and substituting values carefully. |

A stone is thrown vertically upwards with speed $16 \text{ m s}^{-1}$ from a point $h$ metres above the ground. The stone hits the ground $4$ s later. Find
\begin{enumerate}[label=(\alph*)]
\item the value of $h$, [3]
\item the speed of the stone as it hits the ground. [3]
\end{enumerate}
