An elevator has a mass of 1500 kg and is carrying 10 passengers through a height of
15 m from the ground. The time taken to lift the elevator to that height is 0.75 minutes.
Calculate the power required by the motor to lift the elevator if the mass per passenger
is 50 kg.
power = force * distance / time, so
9.81(1500 + 10*50) * 15 / 45 = _____ Watts
