Maybe it remotely engages the brakes. Maybe it has a large "claw" that holds the plane in place. WTF knows? We only know that we're told in the problem that the conveyor belt matches the speed of the wheels. What do we know about a vehicle who's wheels are matched by a conveyor belt in the opposite direction? It stays stationary. This plane aint movin' cuz as soon as it moves fwd relative to the position of conveyor, it has violated a condition of the problem.
I'll put it in terms that I've seen used recently.
I would like somebody to tell me how a plane can take off when it's wheels are not allowed to spin any faster than the conveyor belt it's sitting on which always matches it's wheel speed in the reverse direction? And I don't want to hear any BS about the wheels slipping on the surface of the conveyor or the plane being a harrier.
Solve the problem we're given, not the one in your head that's based on a realistic conveyor.
