Consider the closed-loop system in Figure P5.22, where

(a) If Ñ‚ = 2.43, determine the value of K such that the steady-state error of the closed-loop system response to a unit step input, R(s) = l/s, is zero.
(b) Determine the percent overshoot P.O. and the time to peak Tp of the unit step response when K is as in part (a).
