Physics (AS & A Level) · May / June 2021 · Paper 11 · Question 17

A trolley of mass 600 kg is initially at point P on a slope, at a height of 80 m above ground level, as shown. The trolley is released from rest and moves along the slope, first coming to rest at point Q, at height h above ground level. The total distance PQ moved by the trolley along the slope is 1.5 km. A constant resistive force of 300 N opposes the motion of the trolley on the slope. What is h?

1. A3.5 m
2. B76 m
3. C79 m
4. D80 m
