no, the question says that the treadmill will reverse at the same speed that the plane is moving forward. this has
absolutely nothing to do with what the engine is doing, which is what will actually pull the plane forward. once the place starts pulling forward, that is when the wings/lift come into play. freely spinning wheels affect this in no way whatsoever.
in other words, the only way that plane isn't going to fly is if it's clamped down to the ground.
