Homework Help: Physics- springs

Posted by David E. on Wednesday, April 25, 2012 at 11:54pm.

Block A has a mass 1.00kg, and block B has a 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 egligible 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 A ?
b)- how much potential energy was stored in the compressed spring ?
