In the arrangement shown, two blocks of masses m and 2m affixed on the ends of springs of force constant 2k and k are held at rest. The other ends of the springs are affixed on fixed supports. Relaxed length of each spring is l, distance between the supports is 2l, size of the blocks is negligible and the floor is frictionless. Initially the blocks are held a distance l apart compressing the spring identically. After the blocks are released, they rush towards each other, collide head on and stick to each other. Find maximum speed of the blocks in the ensuing oscillations.
