The diagram below shows a heavy treasure chest being salvaged from the seabed by a research vessel.

A constant upward tension force of 3200 N in the cable lifts the chest vertically through a distance of 18 m.
Calculate the work done by the tension force on the chest.
Use the equation:
work done=force×distance moved in the direction of the force \text{work done} = \text{force} \times \text{distance moved in the direction of the force} work done=force×distance moved in the direction of the forceState the unit of work done.
