Problems 10 and 11: A nonlinear spring has a spring force function of: F =-2x (x+2) (N) 10. What is the spring potential energy function? Answer 10: 11. The spring is positioned horizontally along a frictionless surface. A 2 kg mass is pushed against the spring. By what amount should the spring be compressed so that when the mass is released, the max velocity of the mass is 5 m/s?
