.You are given the unity-feedback system Use MATLAB to plot the root locus.Use a closeup of the locus (from -5to 0 and -1 to 6) to find the gain,K, that

yields a closed-loop unit-step response, c(t), with 20.5%overshoot and a settling time of Ts= 3 seconds. Mark on the time response graph all other relevant characteristics, such as the peak time, rise time, and final steady-state value. \mathrm{G}(\mathrm{s})=\frac{\mathrm{K}(\mathrm{s}+0.02)}{\mathrm{s}^{2}(\mathrm{~s}+4)(\mathrm{s}+10)(\mathrm{s}+25)}
