A boy of mass `50kg` is standing at one end of a boat of length `9m` and mass `400kg`. He runs to the other end. The distance through which the centre of mass of the boat boy system moves is

A boy of mass m is standing at one end of a boat of mass M and length l. The boy walks to the other end, the displacement of the

A man of 50 kg is standing at one end on a boat of length 25m and mass 200kg .If he starts running and when he reaches the other end, has a velocity 2ms^(-1) with respect to the boat.The final velocity of the boat is

A boy of mass 40 kg is standing at one ned of the boat (mass : 80 kg) of length 6m in a river. Now the boy reaches to other end of the boat. Find the distance moved by the boat and the distance travelled by boy as seen from the bank of river.Assume that the system is at rest and no friction between the boat and the water.
