Answer to Question #49291 in Physics for Chelsea

Question

Consider an airliner having a mass of 5x10^4 kg and a total wing area of 1.05x10^2 m2. If the airliner is flying at a velocity of 225m/s and we assume this is also the velocity for the air moving on the underside of the wing, what is the velocity of the air above the wing for the airliner to remain at a fixed altitude. Assume the air has a density of 1.25kg/m3.
