How Fast Does the Elevator Cable Perform Work?

[needhelp1234]

The loaded cab of an elevator has a mass of 3.0 103 kg and moves 165 m up the shaft in 23 s at constant speed. At what average rate does the force from the cable do work on the cab?


I don't know where to begin. The answer is sin kW.

Work is what?

Did I hear you say change in potential energy? Because if I did then I'd be thinking you were on the right track already.
