A powered winch raises a load vertically in two stages. In each stage, the winch exerts a constant force in the direction of the load’s motion.
| Stage | Force exerted by the winch (N) | Distance moved (m) |
|---|---|---|
| First | 500 | 12 |
| Second | unknown | 8.0 |
The total energy transferred by the winch to the load during the two stages is 11 200 J.
Calculate the force exerted by the winch during the second stage.
