Find the final speed of block of given block

Reference no: EM13247879

Block Ahas 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 Bacquires a speed of 1.30m/s .

A. What is the final speed of block A?

B. How much potential energy was stored in the compressed spring?
