Conservation of energy in a spring-masses system

Please see attachments, weights are in pounds force not pounds mass.

Blocks A and B weigh 8lb and 3lb respectively and are connected by a cord-pulley system and released from rest with the spring undeformed. knowing the spring constant K determine the velocity of block B after it has moved 6 inches. The find the maximal velocity and displacement of block B.
