[" Two men of masses "60kg" and "80kg" are at the two ends of a slab of mass "],[160kg" as shown in figure.The horizontal surface is smooth.If the men "],[" interchange their positions on the slab,then displacement of the slab is "]

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 persons A and B are standing at the two opposite ends of a plank of length 4 m as shown in the figure. Plank is kept on a frictionless horizontal surface. Displacement of Plank, when A and B interchange their positions on the plank is (given m_A=40 kg, m_B= 60 kg, m_(plank) = 20 kg)

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)

Two men to masses 80kg and 60kg are standing on a wood plank of mass 100kg , that has been placed over a smooth surface. If both the men start moving towards each other with speeds 1m//s and 2 m//s respectively then find the velocity of the plank by which it starts moving.

Two blocks of mass 2 kg and 4 kg are accelerated with same acceleration by a force 10 N as shown in figure on a smooth horizontal surface. Then the spring force between the two blocks will be (spring is massless)
