Solve the all parts of given question:
Question: To reduce the power requirement of elevator motors, elevators are counterbalanced with weights connected to the elevator by a cable that runs over a pulley at the top of the elevator shaft. Neglect any effects of friction in the pulley. Assume a 1500 kg elevator that carries a maximum load of 800 kg is counterbalanced with a mass of 1900 kg.
Part I: What is the power provided by the motor when the elevator ascends fully loaded at a speed of 1.6 m/s.
IN kW
Part II: How much power is provided by the motor when the elevator ascends at 1.6 m/s without a load?
In kW
Please show work I think I have the answer just not positive. Thank you.
