As shown in the picture below, the 1.5-kg blocks are identical,as are the massless springs. Initially, each spring is compressedby the same amount. If there were only two blocks, then they wouldfly apart at 4 m/s with respect to the track. The system isinitially at rest and frictionless. The springs are set to releaseautomatically in succession, left to right. Find the velocities ofall the blocks. What happens to the center of mass?
