The loaded cab of an elevator has a mass of 3.0 multiplied by 103 kg and moves 161 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?

• physics 11 -

tension on cable=3*103*g
work=tension*distance
powerrate=work/time=tension*height/time
