3. The block diagram given here shows a closed-loop control of a third order plant. Comment on the stability of (i) the open-loop transfer function and (ii) closed-loop transfer function using Routh-Hurwitz stability criterion.

Find the signal flow graph and determine the closed loop transfer function using Mason’s Formula:
how to find the closed loop poles and zeros on a tf like this by hand. With unity feedback.
This is a practice question from my Introduction to Circuits course. I am having a hard time finding the poles for this. When I implement the circuit in LT Spice, I can see that the cutoff frequency is somewhere around 16kHz, but I can't figure out how to come up with that value mathematically. It is underdamped; so, will have imaginary components, but I'm lost as to how to find them or what to do with them or how to come up with the correct cutoff frequency to match LT Spice. Thank you for your assistance.
