Okay...this just made a world of difference. I'll tell you why.
If the conveyer belt is not intellegently designed to match the plane's speed at any moment in time whiles the plane is on the conveyer belt then this is no longer a question of physics but a simple matter of common sense.
Now the question is stating "if a plane if moving faster than an oppossing conveyer belt will the plane take off?"
the answer is YES!
or "On the ground is a plane's pre-flight velocity determined by turbine power on the wings or the drive power of the wheels?"
That I do not know. But If the wheels are not "drive" wheels and the conveyer belt is not intellegent enought to track and match the wheel speed then the plane can outspeed the belt and fly.
but then again if the conveyor belt can match and track the plane's speed then the plane will NOT FLY.
Simply because the turbine push of the turbine-engine can ONLY be express via the plane's wheel speed since the plane is on the ground.
So Komodo to solve this riddle we need to know MORE about that conveyer belt/table cloth/threadmill device.
