Work, average rate problem

  1. Dec 7, 2008 #1
    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.
