Question
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.
