A unity feedback system has the loop transfer function

This system is open-loop unstable.
(a) Determine the range of K so that the closed-loop system is stable.
(b) Sketch the root locus.
(c) Determine the roots for K = 10.
(d) For K = 10, predict the percent overshoot for a step input using Figure 5.13.
(e) Determine the actual overshoot by plotting the response.
