A powered winch pulls a loaded service trolley along a straight track in two stages. The force from the winch acts along the track. The table shows the force from the winch and the distance the trolley moves in each stage.
| Stage | Force from winch (kN) | Distance moved (m) |
|---|---|---|
| 1 | 2.4 | 18 |
| 2 | 1.6 | 12 |
Calculate the total work done by the winch on the trolley.
