| Topic | Travel graphs |
| Type | Velocity-time graph sketching |
| Difficulty | Easy -1.2 This is a straightforward mechanics question requiring only basic SUVAT equations and interpretation of a velocity-time graph. Part (a) is a simple sketch of two linear segments (acceleration then constant velocity), and part (b) involves calculating area under the graph or using s=ut+½at². Both parts are routine applications with no problem-solving insight required, making this easier than average for A-level. |

A cyclist starting from rest accelerates uniformly at $1.5 \text{ m s}^{-2}$ for $4$ s and then travels at constant speed.
\begin{enumerate}[label=(\alph*)]
\item Sketch a velocity-time graph to represent the first $10$ seconds of the cyclist's motion. [2]
\item Calculate the distance travelled by the cyclist in the first $10$ seconds. [2]
\end{enumerate}
