What examiners said
This question was answered well by the majority of candidates. It is necessary to use the principle of conservation of momentum for the collision between particle P and particle Q.
— Examiner report, February/March 2025, 9709/42 Q5(a) (Cambridge)
Again, this part was well done by most. The method used was to apply the principle that the linear momentum of 𝑄 can be equated to the linear momentum of the coalesced particle 𝑄𝑅. This gave the required result of 0.75 ms-1 which was obtained by the majority of candidates.
— Examiner report, February/March 2025, 9709/42 Q5(b) (Cambridge)
This request was found difficult by a significant number of candidates. The most common error seen by examiners was for the use of constant acceleration formulas even though none of the particles were accelerating. The majority of candidates found the time taken for particle Q to reach particle R. Also, many found the distance between P and Q at the instant the collision between Q and R took place...
