| Type | Find acceleration from SUVAT |
| Difficulty | Moderate -0.8 This is a straightforward kinematics question using standard SUVAT equations with constant acceleration. All three parts involve direct application of memorized formulas (v²=u²+2as, v=u+at, and again v²=u²+2as) with no problem-solving insight required. The calculations are routine and the question structure is typical textbook fare, making it easier than average for A-level. |
| Spec | 3.02d Constant acceleration: SUVAT formulae |
An aircraft moves along a straight horizontal runway with constant acceleration. It passes a point $A$ on the runway with speed $16$ m s$^{-1}$. It then passes the point $B$ on the runway with speed $34$ m s$^{-1}$. The distance from $A$ to $B$ is $150$ m.
\begin{enumerate}[label=(\alph*)]
\item Find the acceleration of the aircraft. [3]
\item Find the time taken by the aircraft in moving from $A$ to $B$. [2]
\item Find, to 3 significant figures, the speed of the aircraft when it passes the point mid-way between $A$ and $B$. [2]
\end{enumerate}
