Plane on a treadmill poll...

[Kyle]

in the problem, it states that the plane is moving one way while the belt is moving the opposite way at the same exact speed. Think about it. (-)10 + (+)10 = ZERO. the two speeds cancel each other out and the plane goes nowhere.

I would agree with that if we were talking about something propelled by the wheels, like a bicycle on a treadmill. Then yeah (-)10 + (+)10 = ZERO. But the thrust in this scenario is different.

I think the plane would take off. Even though the wheels are going backwards the plane is moving forward, so I doubt the wheel movement matters. Just a thought.
