a. A spring that required 120 J of work to be stretched 0.2 m from its equilibrium position.
b. A spring that required a force of 200 N to be stretched 0.2 m from its equilibrium position.
a. Set up the integral that gives the work done in stretching the spring 1.75 m from its equilibrium position. Use increasing limits of integration.
