| Topic | Vectors Introduction & 2D |
| Type | Relative velocity: find resultant velocity (magnitude and/or direction) |
| Difficulty | Standard +0.3 This is a straightforward mechanics question involving relative velocity of two objects. It requires basic vector addition/subtraction and understanding of relative motion, which are standard M2 topics with routine application of formulas. The multi-part structure and context make it slightly easier than average. |
| Answer | Marks | Guidance |
|---|---|---|
| \(T = 0.3 \times \frac{s^2}{0.6}\) | M1 | Uses \(\text{acc} = \frac{v^2}{r}\) |
| \(T = 12.5 \text{ N}\) | A1 | [2] |
$T = 0.3 \times \frac{s^2}{0.6}$ | M1 | Uses $\text{acc} = \frac{v^2}{r}$
$T = 12.5 \text{ N}$ | A1 | [2]\includegraphics{figure_1}
\begin{enumerate}[label=(\alph*)]
\item $A$ has velocity $\vec{x}$ and $C$ has velocity $\vec{v}$
\end{enumerate}
