A machine pulls an electrical cable through a conduit in three stages. In each stage, the cable moves along the line of action of the force.
| Stage | Force / N | Distance moved / m |
|---|---|---|
| 1 | 180 | 2.5 |
| 2 | 120 | 4.0 |
| 3 | 90 | not given |
The total work done on the cable during the three stages is 1290 J.
Calculate the distance moved during stage 3.
