SUP3. A small airplane has wings with surface area 9m2 each. The speed of the air across the top of the wing is 50m/sec, and across the bottom of the wing, 40m/sec. Take the density of air to be 1.2kg/m3.
(1) (a) Find the difference in the pressure between the top and the bottom of the wing.
(2) (b) i) Find the net lift upward on the plane.
(3) ii) If there is no other lift on the plane, what would be the mass of the plane? Assume the plane is not accelerating up or down.
