A point mass of 1 Kg collides elastically with a stationary point mass of 5 Kg. After the collision, the 1 Kg mass reverses its
direction and moves with a speed of 2 m/s. Which of the following statement is correct for the system of these two masses?
Total kinetic energy of the system is 6 J
Momentum of the 5 Kg mass after collision is 4 Kg m/s
Kinetic energy of the large mass after collision is 5 J
Total momentum of the system is 3 Kg m/s
