Moving blocks connected by a spring Two Identical 0.15 kg blocks (labeled 1 and 2) are lnltlally at rest on a nearly frictionless surface, connected by an unstretched spring, as shown In the upper diagram, where X2 = 0.05 m. Then a constant force of 8 N to the right is applied to block 2, and at a later time the blocks are in the new positions shown in the lower diagram, where x1 = 0.02 m and X3 = 0.1 m. At this final time, the system is moving to the right and also vibrating, and the spring is stretched.
