As someone pointed out, the problem is the question is badly worded.
"Plane speed" and "the plane moves" are too vague, and there are too many unspecified variables.
It depends on whether you are referring to ground speed, relative to a ground-stationary observer, what the wind is doing.
The plane could be doing 100km/hr ground speed, but with a tail-wind high enough to reduce its *airspeed* below its stall point, it wont take off.
It could be doing 20km/hr into the wind and easily take off.
Assuming the wind to be nil, "plane movement" to refer to ground speed. the plane will take off exactly as normal, the only effect will be that the wheels will be doing twice the apparent ground velocity of the plane.
@George. Again. relative to the ground, he would follow a ballistic arc... relative to the plane (ignoring wind drag), he would go straight up.
think of the old analogy of playing ping pong on a train. Its all about frames of reference and velocity vectors.. stuff your average person isnt used to thinking in
Asking vague questions with trick wording sure is good to get everyone thinking.. _________________ Great minds discuss ideas. Average minds discuss events. Small minds discuss people
