Mr. Verma (50kg) and Mr. Mathur (60kg) are sitting at the two extremes of a 4 m long boat (40 kg) standing still in water. To discuss a mechanics problem, they come to the middle of the boat. Neglecting frictioin with water how far does the boat move on the water during the process?

Father (80 kg) and son (30 kg) are sitting at one of the ends of a 4 m long boat (40 kg) standing still on water. They start to shift slowly. Father stopped at centre of boat but son stopped at other end. Neglecting friction with water, how far does the boat move on the water during the process?

Two boys A and B of masses 60kg and 40kg respectively are at the ends of a 4m long boat of mass 100kg which is on water in lake and the system is at rest.If the boys meet at the centre of the boat then find the displacement of centre of mass of the boat in meter (neglect friction between water and boat)

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.

Two men of masses 40 kg and 20 kg are standing on a boat of mass 100 kg. Length of boat is 20m. Neglect the friction between water and boat. Find the displacement of the boat when both the persons reach at middle of boat.

A 10 kg boy standing in a 40 kg boat floating on water is 20 m away from the shore of the river. If the boy moves 8 m on the boat towards the shore, then how far is he from the shore ? (Assume no friction between boat and water).
