![6. A block of mass m and a block of mass 3m are used to sandwich a massless spring with spring
constant k. The blocks are not connected to the spring. Initially the blocks are at rest on a frictionless
surface, and they are being held together so that the spring between them is compressed by an amount
D from its equilibrium length. The blocks are then released, and the spring pushes them off in opposite
3k
directions. Find the final speeds of the two blocks. [Ans: v,
