Prove that the force of lift Flift on a bird’s wing is given by
the expression:
Flift = ρA (v2top – v2below)
2
where ρ is the density of air, A is the wing area, vtop is the air
speed on the top side of
the wing, and vbelow is the air speed below the wing. For this
problem, assume that air
is incompressible.

I have solved the top speed, the time to reach top
speed, and the speed the plane takes off at.
this is what I have.
I need help on the graphing portion of the
problem
I will give you a Thumbs Up if you solve this part for me. Thank
