# Lift force on an airplane wing

Classical Mechanics Level 2

The air above an airplane wing travels $$200 \text{ m/s}$$, while the air below it travels only $$180 \text{ m/s}$$. Find the magnitude of the lift force if the density of air is $$\rho = 1.29 \text{ kg/m}^3$$ and the area of the wing is $$A = 2\text{ m}$$.

Assume the height of the wing is negligible.
