Many candidates found this question challenging. Many multiplied 360 by 1.6. Some thought that
— Examiner report, May/June 2025, 0972/31 Q3(b) (Cambridge)
There were many correct answers for force C, but some confusion between force and energy was seen, such as the incorrect answer ‘gravitational potential energy’. Answers for force D tended to be too vague, e.g. ‘backwards force’ or ‘stopping force’.
— Examiner report, May/June 2025, 0972/32 Q1(b)(i) (Cambridge)
Candidates needed to recognise that as the car was decelerating, the resultant force would act in a backwards direction. Consequently, force B would be less than force D. Many gave the incorrect answer of 2800 N for force B. This would give a resultant force of zero meaning the car would travel at a constant speed.
