Two persons of masses `55 kg` and `65 kg` respectively are at the opposite ends of a boat. The length of the boat is `3.0 m` and weights `100 kg`. The `55 kg` man walks up to the `65 kg` man and sits with him. If the boat is in still water the centre of mass of the system shifts by.

Two persons A and B of weight 80 kg and 50 kg respectively are standing at opposite ends of a boat of mass 70 kg and length 2 m at rest. When they interchange their positions then displacement of the centre of mass of the boat will be :-

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)

The base area of a boat is 2m^(2) . A man weighing 76kg weight steps onto the boat. Find the depth to which the boat will sink further in water
