homework and exercises - Moments of vibrating string


I have to calculate first 10 moments for vibrating string with damping, but I don't know how to do it. I read about moments and in definition they mention linear system $$x'=Ax+Bu, \qquad y=Cx$$ with transfer function $$W(s)=C(sI-A)^{-1}B.$$ Then kth moment of a system above is $$C(sI-A)^{-(k+1)}B.$$ But for a vibrating string I know only wave equation $$Mx''+Cx'+Kx=b(t).$$ How to transform it to linear system?

Understanding Stagnation point in pitot fluid

What is stagnation point in fluid mechanics. At the open end of the pitot tube the velocity of the fluid becomes zero.But that should result...
