One of the most powerful cranes in the world functions in Switzerland. This can slowly increase a load of M = 5800 tones to a height of h = 11.0 m (1 tone = 1000 kg).
(i) Determine how much work is done by the crane?
(ii) If it takes 1.00 min to elevate the load at constant velocity to this height, determine the power build up by the crane.
