| Topic | Constant acceleration (SUVAT) |
| Type | SUVAT simultaneous equations: find u and a |
| Difficulty | Moderate -0.3 This is a straightforward two-unknown SUVAT problem requiring simultaneous solution of two standard equations (s = ut + ½at² and v = u + at). While it involves algebraic manipulation with two unknowns rather than direct substitution, the setup is routine and the mathematics is standard for AS-level mechanics with no conceptual challenges. |
| Spec | 3.02d Constant acceleration: SUVAT formulae |
\begin{enumerate}
\item 10 seconds after passing a warning signal, a train is travelling at $18 m s ^ { - 1 }$ and has gone 215 m beyond the signal. Find the acceleration (assumed to be constant) of the train during the 10 seconds and its velocity as it passed the signal.
\end{enumerate}
