-1
16. A ball A of mass 1 kg moving at a velocity of 4 m s collides with ball B of mass 2 kg
which is at rest. Calculate the velocity of both balls after collision if the collision is an
elastic collision. [5 m]

-1
17. Ball A of mass 400 g and velocity 4 m s collides with ball B of mass 600 g and
-1
velocity 10 m s . After collision, A and B will move together. Determine the final
velocity of both balls if A and B moves in the opposite direction initially. [2 m]

mass 2 kg at rest. Determine the velocity of each toy car after collision if the collision is
elastic. [7 m]
