Use Conservation of Energy methods to solve the following: A 27 lb box is placed on top of two concentric springs. Spring one (k1=218 lb/in) is on the outside of spring two (k2=106 lb/in). The box was pushed downward such that the displacement of the springs were x1=3 in. and x2= 8 in. and then released. Find the maximum height, h, that the box will reach.
