Air streams horizontally past a small airplane's wings such that the speed is 70.0 m/s over the top surface and 50.0 m/s past the bottom surface. If the plane has a mass of 600 kg and the TOTAL area of the two wings is 9.00 m2, what is the net vertical force (including the effects of gravity) on the airplane?

Air streams horizontally past a small airplane's wings such that the speed is 70.0 m/s over the top surface and 60 m/s past the bottom surface. If the density of air is 1.20 kg/m^3, what is the lift due to pressure difference on the wing, assumed to be very thin and having an area 16.2 m^2 ? If you wanted to calculate the net lift on the wing using only the physics learnt in this class, what other data value(s)...
An airplane has a mass of 2.7×106 kg , and the air flows past the lower surface of the wings at 85 m/s . If the wings have a surface area of 1500 m'2 , how fast must the air flow over the upper surface of the wing if the plane is to stay in the air?
An airplane has a mass of 2.2×106 kg , and the air flows past the lower surface of the wings at 85 m/s . If the wings have a surface area of 1200 m2 , how fast must the air flow over the upper surface of the wing if the plane is to stay in the air?
An airplane has a mass of 3.0×106 kg , and the air flows past the lower surface of the wings at 83 m/s . Part A If the wings have a surface area of 1600 m2 , how fast must the air flow over the upper surface of the wing if the plane is to stay in the air?
An airplane has a mass of 1.6×106 kg , and the air flows past the lower surface of the wings at 92 m/s. If the wings have a surface area of 1000 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 using two significant figures.
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.
An airplane has a mass of 2.4×106 kg , and the air flows past the lower surface of the wings at 91 m/s . Part A If the wings have a surface area of 1200 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.
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.
