Q2) Answer the followings

2.1 Given the following forward transfer function:

G(s) = 100/ (𝑠 (𝑠+8) (𝑠+15))

workout the stability status of the feedback control system for a unity feedback control loop using Routh Hurwitz approach.

2.2. Assume the constant value (100) used in the forward transfer function stated in 2.1 above is replaced by K so that the transfer function become as follows:

G(s) = K/ (𝑠 (𝑠+8) (𝑠+15))

Workout the upper and lower boundaries of K for the feedback control system to be stable
