Solve the problem.Hooke's law is applicable to idealized (linear) springs that are not stretched or compressed too far. Consider a nonlinear spring whose restoring force is given by F(x) = 17x - 0.2x3, for |x| ? 9. How much work is done in compressing the spring from its equilibrium position (x = 0) to x = -2? Round to two decimal places when appropriate.
