| Topic | Momentum and Collisions |
| Type | Direct collision, find final speed |
| Difficulty | Moderate -0.8 This is a straightforward M1 momentum conservation question with two standard parts: (a) direct application of conservation of momentum with one unknown, and (b) similar application with algebraic unknowns. Both parts require only substitution into momentum equations with no conceptual challenges or multi-step reasoning beyond basic algebra. |
| Spec | 6.03a Linear momentum: p = mv6.03b Conservation of momentum: 1D two particles |
I've reviewed your submission, but it appears to only contain the question number and six "1"s without any actual mark scheme content to clean up.
Could you please provide the actual mark scheme content that needs to be formatted? I'll need the marking points (M1, A1, B1, etc.) along with their descriptions so I can:
- Convert unicode symbols to LaTeX notation
- Format clearly with one marking point per line
- Preserve all marking annotations and guidance notes
Please paste the full mark scheme content you'd like me to process.1 A particle $A$ moves across a smooth horizontal surface in a straight line. The particle $A$ has mass 2 kg and speed $6 \mathrm {~m} \mathrm {~s} ^ { - 1 }$. A particle $B$, which has mass 3 kg , is at rest on the surface. The particle $A$ collides with the particle $B$.\\

\begin{enumerate}[label=(\alph*)]
\item If, after the collision, $A$ is at rest and $B$ moves away from $A$, find the speed of $B$.
\item If, after the collision, $A$ and $B$ move away from each other with speeds $v \mathrm {~m} \mathrm {~s} ^ { - 1 }$ and $4 v \mathrm {~m} \mathrm {~s} ^ { - 1 }$ respectively, as shown in the diagram below, find the value of $v$.\\
