Physics (AS & A Level) · Oct / Nov 2024 · Paper 13 · Question 19

A weight W hangs from a trolley that runs along a rail. The trolley moves horizontally through a distance p and simultaneously raises the weight through a height q. As a result, the weight moves through a distance r from X to Y. It starts and finishes at rest. How much work is done on the weight during this process?

1. AWp
2. BW(p + q)
3. CWq
4. DWr
