What examiners said
Most responses appreciated the need to apply the conservation of linear momentum to find the velocity of the combined particle R after collision to then be able to calculate the loss of kinetic energy due to the collision. It was quite common to see the initial projection speed of P used instead of the given answer in part (a). Furthermore, it was also common to see responses using an incorrect ma...
— Examiner report, October/November 2023, 9709/41 Q4(b) (Cambridge)
This part was answered extremely well. The most common error was to give the power developed by the engine of the car in W rather than the required kW.
— Examiner report, October/November 2023, 9709/41 Q6(a)(i) (Cambridge)
This part was also answered well, with many responses correctly using their value from part (a)(i) to find the required driving force of the car, before correctly applying Newton’s second law to find the required acceleration. The most common errors were either to misinterpret that power had increased by 9 kW and assume instead that the power was now 9 kW, or to not include the resistive force in...
