Two smooth spheres, A & B of equal 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 $5 \hat{i} + 2 \hat{j}$ and $2 \hat{i} - \hat{j}$ 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
