2. For the system shown in figure: G(s) = K/(s+5)(s+20)(s+50) Do the following: a. Draw the Bode log-magnitude and phase plots. b. Find the range of k for stability from your Bode plots. b. Find the range of k for stability from your Bode plots. c. Evaluate gain margin, phase margin, zero dB frequncy, and 180 frequency from your Bode plots for k=10.000
