Ok, so add your moving runway to the picture. The plane comes it at 200mph again, the wheels hit the runway, which is going backwards at 200 mph, so what happens? does the plane instantly stop, ignoring the laws of momentum?!

no, the wheels go BRIRP! and spin up to 400mph, the pilot hits the throttle again and does his 'touch and go', just as before.

The engines on a plane do not react off the runway. If they did, then how do planes in alaska with skis instead of wheels get off the ground?!

whoa i had completely forgotten about those.... i had to actually look at the problem again.... and i found

"A plane is standing on a runway....

so you cannot use that as an example.
