A process that exhibits second-order dynamics has the following transfer function: G(s)=18s2+12s+360 A unit step input change is made to this process at time t=0. a. What are the gain (unitless), time constant (in minutes), and damping coefficient (unitless) according to this transfer function? Is the experience an overdamped, critically damped, or underdamped response? b. What will be the percent overshoot of the response? c. At what time will the response reach its first maximum value
