So how does it reach that speed if the ground is always moving back at a speed greater than the speed at which it can propel itself forwards?
You've kind of answered your own question there…..'propel itself forwards' is what you wrote….
How does it do this??
Does the plane rely on:
a) the wheels which are just fitted to free spinnig hubs so the plane has something to sit on & move around the ground on, or
b) the great big propeller/jet engine that has no contact with the ground and pushes heaps of air backwards
to propel itself along…..??
If your answer is a) you are wrong.
If your answer is b) you are correct.
Considering that you went for b), then the little wheels can be doing whatever they want against a conveyor/hundreds of marbles/zilions of ants running the wrong way but the propeller/jet engine is still gonna be pushing air backwards causing the plane to move forwards………
