57 A winch is driven by an electric motor with a separate excitation and fed from a battery of emf 300 V The rope and the hook of the winch rise at a velocity v 4 m s without a load and at a velocity v 1 m s with a load of mass m 10 kg Anode 127V Cathode DE Fig 110 Fig 111 Determine the velocity v of the load and its mass m for which the winch has the maximum power neglecting the mass of the rope and the hook
