Part A
Block A in the figure (Figure 1) has mass 1.00 kg, and block B 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 1.40 m/s.
