No, that is not the question. From the OP:
Quote:"Imagine a 747 is sitting on a conveyor belt, as wide and long as a runway. The conveyor belt is designed to exactly match the speed of the wheels, moving in the opposite direction. Can the plane take off?"
If wheel and treadmill speed match, velocity of the wing through the air = 0. How could it be otherwise?
Sounds like you're getting things mixed up.
Again, basic.
