Blocks A (mass 4.00 kg) and block B (mass 2.00 kg) are on a horiz frictionless surface. A light spring is compressed between them, storing 54.0 J of elastic potential enugy. The two blocks are released from rest and move off in opposite directions. What is the final speed of block B, after leaving the spring
