An electric winch is used to pull a rescue capsule vertically upwards from a subterranean cave floor to the surface, as shown in the diagram.
The surface is 65 m vertically above the cave floor.
The rescue capsule has a total mass of 380 kg.
Calculate the increase in gravitational potential energy of the rescue capsule as it is lifted from the cave floor to the surface.
gravitational field strength, g=9.8 N/kgg = 9.8\text{ N/kg}g=9.8 N/kg
