Air streams horizontally across an aeroplane wing of area ${\displaystyle 3}{{\displaystyle m}}^{{\displaystyle 2}}$ weighting ${\displaystyle 250}{\displaystyle kg}$ .  The air speed is ${\displaystyle 60}{\displaystyle m/s}$  and ${\displaystyle 45}{\displaystyle m/s}$ over  the top surface and under the bottom surface respectively.  What is the lift on the wing? (Density of air 1.293 g/l)
