An elevator cab in the New York Marriott Marquis has a mass of 4.96 x 103 kg and can carry a maximum load of 1.80 x 103 kg. If the cab is moving upward at full load at 3.71 m/s, what power is required of the force moving the cab to maintain that speed?

Add the elevator mass and the load mass. Multiply the sum by g to get the cable tension in Newtons. The product of cable tension and velocity is the power required, in Watts. If it were accleerating, still more power would be needed.
