Block A in (Figure 1) has mass 0.800 kg, and block B has mass 2.85 kg. The blocks are forced together, compressing a spring S between them; then the system is released from rest on a level, frictionless surface. The spring, which has negligible mass, is not fastened to either block and drops to the surface after it has expanded. Block B acquires a speed of 1.30 m/s.
