Describe the Newton's second law.
in simple terms: sum of forces is equals to mass times acceleration.(change of momentum with change of time)
What is the derivative of the following function? (with respect to x) f(x)= 2x^2+4y
What is the purpose of canard in subsonic/supersonic speed regimes?
More stability as the center of gravity shifts behind neutral point. also it is an extra control surface when we don't use horizontal tail.
