Two smooth spheres, A & B of equals radius, lie on a horizontal table. A is of mass m & B is of mass 3m. The spheres are projected towards each other with velocity vectors 5hat(i) + 2hat(j) and 2hat(i) - 2hat(j) respectively & when they collide, the line joining their centres is parallel to the vector hat(i). If the coefficient of restitution between A and B is 1/3 The loss in kinetic energy caused by the collision is
