The overall transfer function of a second-order process is given by: G(s)=36s2+10s+120 a. What kind of damping is prevalent here? Why? (5 marks) b. What is the time constant and damping coefficient of the 2nd order process shown above? (5 marks) c. What are the individual time constants of the first order processes constituting the second-order process given above? ( 10 marks) d. For a step change of magnitude 2, find the output response as a function of time. ( 10 marks) e. What is the time required for the output to settle at 95% of maximum output value? Find this time by substituting t in terms of at ,5,10 and 15. By doing this, find which time is the closest to the answer among the 4 value you substitute
