A mechanism moves a scenery panel along a straight horizontal track in two stages. In each stage, the force exerted by the mechanism acts in the direction in which the panel moves.
The total work done by the mechanism is 4.80 kJ.
During the first stage, the mechanism exerts a constant force of 320 N over a distance of 6.0 m.
During the second stage, the panel moves 8.0 m while the mechanism exerts a different constant force.
Calculate the force exerted by the mechanism during the second stage.
