It takes an elevator 3.1 minutes to raise a vehicle with a mass of 420 kg from the floor to a height of 8 meters. What size (power) motor (in watts) does it take to do the job?  Hint: this is a multiple step problem in which you must derive the variables needed to solve for problem in step one and then apply those values to the final solution of the problem.  Watch your units.
