| Topic | Constant acceleration (SUVAT) |
| Type | Time to reach midpoint or specific position |
| Difficulty | Easy -1.2 This is a straightforward SUVAT question requiring direct application of standard kinematic equations with no problem-solving insight needed. Part (a) is a 'show that' using v=u+at, part (b) uses s=ut+½at² or v²=u²+2as, and part (c) applies the same formula at the midpoint. All three parts are routine textbook exercises with clearly signposted methods. |
| Spec | 3.02d Constant acceleration: SUVAT formulae |
A racing car moves with constant acceleration along a straight horizontal road. It passes the point $O$ with speed 12 m s$^{-1}$. It passes the point $A$ 4 s later with speed 60 m s$^{-1}$.
\begin{enumerate}[label=(\alph*)]
\item Show that the acceleration of the car is 12 m s$^{-2}$. [2]
\item Find the distance $OA$. [3]
\end{enumerate}
The point $B$ is the mid-point of $OA$.
\begin{enumerate}[label=(\alph*)]
\setcounter{enumi}{2}
\item Find, to 3 significant figures, the speed of the car when it passes $B$. [3]
\end{enumerate}
