| Topic | Constant acceleration (SUVAT) |
| Type | Average speed or total distance calculation |
| Difficulty | Easy -1.2 This is a straightforward SUVAT question with standard bookwork calculations. Part (a) uses s=ut+½at² with u=0, part (b) is a 'show that' using v=u+at, parts (c) and (d) are simple speed=distance/time applications. All steps are routine with no problem-solving or insight required—easier than average A-level. |
| Spec | 3.02d Constant acceleration: SUVAT formulae |
2 A sprinter accelerates from rest at a constant rate for the first 10 metres of a 100 -metre race. He takes 2.5 seconds to run the first 10 metres.
\begin{enumerate}[label=(\alph*)]
\item Find the acceleration of the sprinter during the first 2.5 seconds of the race.
\item Show that the speed of the sprinter at the end of the first 2.5 seconds of the race is $8 \mathrm {~m} \mathrm {~s} ^ { - 1 }$.
\item The sprinter completes the 100 -metre race, travelling the remaining 90 metres at a constant speed of $8 \mathrm {~m} \mathrm {~s} ^ { - 1 }$. Find the total time taken for the sprinter to travel the 100 metres.
\item Calculate the average speed of the sprinter during the 100 -metre race.
\end{enumerate}
