  1. A spring of spring constant k=8.250 N is displaced from equilibrium by a distance of 0.1500 m.  (a) What is the stored energy in the form of spring potential energy?  (b) What was the work done in stretching the spring from its equilibrium position to a displacement of 0.1500 m?  (c) If the spring is stretched from the displacement of 0.1500 m to a displacement of 0.3500 m, what is the change in spring potential energy between those two positions?
