(a) Find the pressure difference on an airplane wing where air flows over the upper surface with a speed of 126 m/s, and along the bottom surface with a speed of 101 m/s.(kPa)
(b) If the area of the wing is 30 m2, what is the net upward force exerted on the wing? (kN)

pressure difference= 1/2 densityair(V1^2V2^2)
