Air streams past a small airplane's wings such that speed is 50 m/s over the top surface and 30m/s past the bottom. If the plane has a wing of 9m^2. Ignoring the small height difference find 1.The pressure difference between the top and bottom of the plane's wings. 2. What would be the gravitational pull on the plane assuming the plane is moving horizontally. .
Draw a right-handed 3D Cartesian coordinate system (= x, y and z axes). Show a vector A with tail in the origin and sticking out in the positive x, y and z directions. Show the angles between A and the positive x, y and z axes, and call these angles α₁, α₂ and α3 Prove that Ax Acos α₁ Ay = Acos α₂ A₂- Acos α3
