Block A in the figure (Figure 1) has a mass of 1.00 kg, and block B has a mass of 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 1.60 m/s.
a) What is the Final speed of block A? 

(b) How much potential energy was stored in the compressed spring?
