Again, the conveyor is supposed to only match the plane's speed, and it only acts on the plane's wheels. Thus, the wheels are moving twice as fast, but the plane is still moving at the same speed.

Duh, my mistake, the answer should be NO... because by the time the plane has reached its 150 mph take-off speed, the wheels are going 300 mph, and they'll overheat, blow-out, and the wheel hubs will catch in the conveyor belt, causing it to seize, and tons of metal airplane and steel-plated conveyor belt strips will be flying through the air at speeds of over 100 mph...

I can just imagine it now...

Again, trick question... because the conveyor moves with speed, and speed does not equal force. That's why a water skier can be doing 40 mph over the water while only holding on to a line with arms that can't even push him at 10 mph... because he's exerting more force on the line with his arms than the water is exerting on his feet.
