For k = 2 N/m, m = 20 g, and c = 0.03 N-s/m, calculate and plot the magnitude (in m/N) and phase (in degrees) of the frequency response function from the excitation f(t) to the response x(t). Show your plots over a frequency range of 0 Hz to 3 Hz, which should include the resonance peak (be sure to check units).
