An airplane has two wings, each with area 5.00 m2, designed so that air flows over the top of the wing at 240 m/s and underneath the wing at 220 m/s. What is the mass of the airplane such that the lift on the plane will support its weight, in 103 kg?. Note. Assume the force from the pressure difference across the wings is directed straight upward. Density of air is 1.29 kg/m3.
