Air streams horizontally past a small airplane's wings such that the speed is 69.5m/s over the top surface and 62.0m/s past the bottom surface. If the plane has mass 1400kg and a wing area of 16.4m^2 , what is the direction of the net vertical force and it magnitude (including the effects of gravity) on the airplane? The density of the air is 1.2kg/m^3
