An airplane has a mass of 2.1×106 kg , and the air flows past the lower surface of the wings at 96 m/s
If the wings have a surface area of 1500 m2 , how fast must the air flow over the upper surface of the wing if the plane is to stay in the air?
Express your answer to two significant figures and include the appropriate units.

If air flows under the wing of.an 80,000 kg plane with a speed of 280 m/s how fast does it need to flow over the top of the wing in order to keep the plane in the air if the wings have a surface area of 60 m2?
Find the pressure difference on an airplane wing if air flows over the upper surface with a speed of 115 m/s , and along the bottom surface with a speed of 103 m/s . Answer is in kPa. If the area of the wing is 33 m2 , what is the net upward force exerted on the wing? Express your answer using two significant figures. Answer in kN
A small jet airplane has a total wing area of 62.5 m2 and a mass of 7.03 104 kg. (a) If this jet is in horizontal flight, determine the pressure difference between the lower and upper surfaces of the wings. (b) When the speed of air traveling over the wing is 237 m/s, determine the speed of air under the wing. Use 1.29 kg/m3 as the density of air.
If the speed of flow past the lower surface of an airplane wing is 101 m/s, what speed of flow over the upper surface will give a pressure difference of 889 Pa between upper and lower surfaces? Take the density of air to be 1.30 × 10-3 g/cm3. Assume the lower surface is at the higher pressure.
For an airplane in flight, the average speed of the air relative to the plane is 317 m/s below the wings and 348 m/s above the wings. The bottom of each wing has a surface area of 29.9 m2. Calculate the lift, which is the net upward force of air on the plane.
For an airplane in flight, the average speed of the air relative to the plane is 306 m/s below the wings and 336 m/s above the wings (see the figure below). The bottom of each wing has a surface area of 29.7 m2. Calculate the lift, which is the net upward force of air on the plane.
For an airplane in flight, the average speed of the air relative to the plane is 320 m/s below the wings and 352 m/s above the wings (see the figure below). The bottom of each wing has a surface area of 30.9 m2. Calculate the lift, which is the net upward force of air on the plane.
7.) A Cessna 152 is a small airplane with a mass of 725 kg and a wing area of 15.0 m. It the wings are designed so that the air flows 13.5% faster above the wings than below, then what is the minimum cruising speed of the plane? (You can make the assumption that all the litt force comes from this difference in air flow.)
