A rope is stretched between two stationary boats on the surface of a lake. A man in the first boat pulls the rope with a constant force of 100 N. The distance between the boats is 100 m in the beginning. The mass of the first boat with the man is 250 kg ,while the mass of the other is 500 kg. Find :(i) the velocity of approach of the two boats 15 s after the start,(ii) the time taken for the two boats to meet each other. [Hint: Consider relative acceleration and apply kinematic equations.]
