1. A) Find and plot closed-loop pole locations of the system below for K=0, 10, 25, 40, 50 B) Calculate the angles and magnitude of the closed-loop transfer function for

each of the poles depending on the K above. C) Plot closed loop time response for each closed loop transfer function for K = 0, 10, 25, 40, 50. D) Discuss the transient response: pole locations and time response. E) Discuss the steady-state response.
