An airplane with a mass of 2.2 x106 kg. has the air flow past the lowersurface of the wings at 80 m/s. If thewings have a surface area of 1200 m2, how fast must theair flow over the upper surface of the wing if the plane is to stayin the air? Consider only the Bernoulli effect.
_____m/s
determine the maximum height attained by the 2.1-kg mass
