A block of mass ‘4 in’ travelling at a velocity v1 in X - direction on a frictionless horizontal plane makes a head-on collision with another block of mass ‘2 m‘ travelling in opposite direction with a velocity v2. After collision both the blocks travel as a single block along X-direction with a final velocity 5 v2 . The ratio of velocities

v1

v2
