A smooth sphere A of 2kg moves with e velocity of 10ms-1 and collides with a stationary sphere B of mass 3kg. The coefficient of restitution is e. Show that the velocity of the first sphere A after collision is (4-6e) and find a similar expression for the velocity of B after the collision.

Calculate the KENETIC ENERGY of each sphere before and after the collision [clue - Ke = 1/2 mv(squared) ]

.. and assume that the total Energy of the system is conserved .. (i.e. no losses).
