A rope is strecthed between two boats at rest. A sailor in the first boat pulls the rope with a constant force of 100N. First boat with the sailor has mass of 250kg. Whereas the mass of second boat is double of this mass. If the initial distance between the boats was 100m. The time taken for two boats to meet each other is (neglect water resistance between boats and water)

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.]

A man of mass m walks from end A to the other end B of a boat of mass M and length l. The coefficient of friction between the man and the boat is mu an neglect any resistive force between the boat and the water.

A man of mass m walks from end A to the other end B of a boat of mass M and length l. The coefficient of friction between the man and the boat is mu an neglect any resistive force between the boat and the water.

When a sailor jumps from a boat to the river bank?

A boat of 90 kg is floating in still water. A boy of mass 30 kg walks from the stern to the bow. The length of the boat is 3 m. Calculate the distance through which the boat will move.

A man weighing 70 kg is standing at the centre of a flat boat of mass 350 kg. The man who is at a distance of 10 m from the shore walks 2 m towards it and stops. How far will he be from the shore? Assume the boat to be of uniform thickness and neglect friction between boat and water?
