Two identical 0.12 kg blocks (labeled 1 and 2) are initially at rest on a nearly frictionless surface, connected by an unstretched spring, where x2 = 0.05 m. Then a constant force of 12 N to the right is applied to block 2, and at a later time the blocks are in the new positions,, where x1 = 0.01 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.
The force was applied to a location on the right hand edge of block 2.
How much work was done on the real system.
