unlike a person on a treadmill, the plane doesnt use its wheels(feet) to accelerate

nice find, nice debate
but still though...if the planes thrusts speed up causing it to move forward wouldnt the conveyer also speed up not allowing it...bah this question is to vague

The plane pushes forward with it's engines, not the wheels. The conveyer will just cause the wheels to spin.
It's like pushing a car on ice, it doesn't matter what way or speed the wheels are spinning, you can still push the car.

I retract my earlier statement and now say the play will fly. The trust from the engines is what will move the plane foward even thought its on a conveyor. The engines will move the fluid around it, the air, and be able to move the plane forward. If you doubt this is the case, take a look at howstuffworks.com and look up jet engines.

alright to clear the air. there seems to be many different answers to this question. it all depends on how you look at the problem.
since we are not told of any form of friction we are to ACT AS IF IT DOES NOT EXIST
therefore what we have are 2 forces, a force a on the plane which is in the positive direction and a force b in the negative direction on the conveyor section under the plane.
since there is no friciton in the wheels nothing is transfered from the conveyor to the plane.
it can take off becuase the plane moves freely fromt eh conveyor. the conveyor has no effect on the plane whatsoever
yes i had it wrong before, and yes this is the right answer i called up a physics professor of 25 years to confirm my new suspicsions
