Two blocks, of mass $1\, kg$ and $2\, kg$ respectively, are connected by a spring and kept on a frictionless table. The blocks are pulled apart, so that the spring is stretched, and released from rest. At a certain instant of time, the block of mass $1 \,kg$, is found to be moving at a speed $2 \,m / s$. What must be the speed of the other block at this instant?
