A 1.0 times 10^3 kg elevator carries a maximum load of 800.0 kg. A constant frictional force of 4.0 times 10^3 N retards the elevator’s motion upward. What minimum power, in kilowatts, must the motor deliver to lift the fully loaded elevator at a constant speed of 3.00 m/s?
I don't know what to do here. I don't want the answer, I just want to know how to get the power when dealing with a frictional force. Help! Oh, and thanks for whoever helps.
