A weight of 200kg hangs freely from the end of a rope. The weight is hauled up vertically from rest by winding up the rope. The pull starts at 250 kg and diminishes uniformly at the rate of one kg per metre wound up. Find the velocity after 30 metres have been wound up. Neglect the weight ofthe rope.
