Homework Statement

What is the net upward force on an airplane wing of area 20 m2 if the speed of air flow is 300 m/s across the top and 280 m/s across the bottom.

Homework Equations

The Attempt at a Solution

I have a feeling that this is an easy question, but i just don't know how to solve it! Any hints would be greatly appreciated.

Hint: there is a lift force is because the pressure on the top and bottom surfaces of the wing are different.

What equations do you know that relate pressure in a fluid to the speed of flow?

So that would be Bernoulli's equation, right?
But how would you use that in this case?
