A second order mechanical system 40x^.. + 80x^. + 1000x = f(t) is identified. The system is subjected to three separate input excitations a. unit initial displacement and
b. unit initial velocity
Plot the displacement response of the system due to these conditions on the three plots provided. Please write (not derive) the generic equation describing the response. Compute the period and identify the response type (over, under or critically damped) for each case.
