Question

In two seperate collisions, the coefficient of restitutions e_1 and e_2 are in the ratio 3:1. In the first collision the relative velocity of approach is twice the relative velocity of seperation. Then, the ratio between the relative velocity of aproach and relative velocity of seperation in second collision is (1) 1:6 (2) 2:3 (3) 3:2 (4) 6:1
