A block of mass 5 kg moves from left to right with a velocity of 2ms^(-1) and collides with another block of mass 3 kg moving along the same line in the opposite direction with velocity 4 ms^(-1) . (i) If the collision is perfectly elastic, determine velocities of both the blocks after their collision. (ii) If coefficient of restitution is 0.6, determine velocities of both the blocks after their collision.
