What power must the motor deliver at a instantaneous speed

Reference no: EM13653040

An elevator has a mass of 1170kg and carries a maximum load of 786 kg. A constant frictional force of 4260 N retards its motion upward. The acceleration of gravity is 9.8 m/s2. What power must the motor deliver at a instantaneous speed of 3.36 m/s if the elevator is designed to provide an upward acceleration of 1.08 m/s2?

Answer in units of W.
