what is the net vertical force (including the effects of gravity) on the airplane?

Question

Air streams horizontally past a small airplane's wings such that the speed is 75.0 m/s over the top surface and 57.0 m/s past the bottom surface.
The plane has mass 1420 Kg and a wing area of 16.1 m^2 , The density of the air is 1.20 kg/m^3.

Answer 1

Crack the book and read about Bernoulli's law.
