For a uniform lifting of a load of mass m, the angular velocity of the lift motor shaft ω = ω0 (1 − m/m_0), where ω0 is the angular velocity of the shaft in the absence of a load, and m_0 is the mass of the heaviest load that can be lifted on this lift. How does the lift's net power depend on the angular velocity of the shaft? What portions do you need to lift the load in order to raise the highest weight to a certain height in a certain time?
