Consider the model of the free damped nonlinear pendulum given by d2() d() . - 2 + 2A-+ w2 sm(J = 0. dt dt Use a numerical solver to investigate whether the motion in the two cases A2 - w2 > 0 and A2 - w2 < 0 corresponds, respectively, to the overdamped and underdamped cases discussed in Section 3.8 for spring/mass systems. Choose appropriate initial conditions and values of A and w.
