What is the magnitude of the net vertical force for a plane?

Air streams horizontally past a small airplane's wings such that the speed is 68.0 m/s over the top surface and 58.0 m/s past the bottom surface.

If the plane has a mass of 1380 kg and a wing area of 16.2 m^2 what is the magnitude of the net vertical force (including the effects of gravity) on the airplane? The density of the air is 1.20 kg/m^3.What is the magnitude of the net vertical force for a plane?volumn of air over the surface

= 68 * 16.2 m3/s

volumn of air under the surface

= 58 * 16.2 m3/s

total upward thrust by air

=[ 68 + 58 ] * 16.2 m3 /s* 1.20 kg/m^3 * 9.81

= 24029N



Weight

=1380 *9.81

=13537.8



the magnitude of the net vertical force (including the effects of gravity) on the airplane



= 24029 - 13537.8

= 10491.2 N
