A motor moves a roof panel along a straight rail. The motor's force acts along the rail and is constant during each stage.
| Stage | Force | Distance moved in the direction of the force |
|---|---|---|
| 1 | 320 N | 0.80 m |
| 2 | 220 N | 1.20 m |
A replacement motor moves the panel through the same total distance and does the same total work, but exerts a constant force throughout.
Calculate the force exerted by the replacement motor.
