Four inelastic cables are attached to a 2-lb plate P. They hold the 15 in-long spring A 3in. in compression when no weight is on the plate. In addition, there is an un-deformed spring B nested within this compressed spring. If the Block C, having a weight of 10 lb, is initially pushed downward such that the plate is 7 in from the surface, determine the maximum height to which the block will rise when released from this position. (Ka = 150 lb/ft and Kb = 300 lb/ft)
