I know that in an equation such that ¨x+ω2x=0,
the angular frequency =ω. But why is that ever √V″(x0)/m? (where x0 is the equilibrium point). I just saw that used in the solutions to a problem set without explanation.
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...
