A point mass 1 kg collides elastically with a stationary point mass of 5 kg. After their collision, the 1 kg mass reverses its direction and moves with a speed of 2 m/s. For the system of these two masses the KE of the centre of mass is

A body of mass 4kg moving with a speed of 3 ms^(-1) collides head on with a body of mass 3 kg moving in the opposite direction at a speed of 2 ms^(-1) . The first body stops after the collision. The final velocity of the second body is

A ball of mass 1 kg moving with a velocity of "0.4 ms"^(-1) collides with another stationary ball. After the collision, the first ball moves with a velocity of 0.3ms^(1) in a direction making an angle of 90^(@) with its initial direction. The momentum of the second ball after the collision will be (in kg ms^(-1) )
