This may have been posted here before, so apologies if so. Here is a little Physics conundrum:
The problem goes like this:
An aircraft is standing on a runway that can move (a conveyor belt). The aircraft moves in one direction, while the conveyor belt moves in the opposite direction. This conveyor has a control system that tracks the aircraft's speed and tunes the speed of the conveyor to be exactly the same, but in the opposite direction. There is no wind. The pilot begins to add thrust to the engines...
The question is:
Will the plane take off or not?
