    Block A in the figure (Figure 1) has mass 1.00 kg, and block has mass 3.00 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 1.20m/s . A) What is the final speed of block ? -...
