Well I surely can't argue the point. I had to ask a 5th grader.
Here is my equation. 180 bucks a month for Kumon = When Daddy needs you to calculate how many yards of concrete I'll call you during lunchtime.
She's had her Turkey sandwich on croissant and a swirl ice cream so she's happy.

Thats MR Hoss to you buddy!
The REAL question is this...
If an airplane is trying to take off on a conveyor belt that always matches the exact speed of the wheels but in the opposite direction will the airplane ever move??

----- Man, now that is a good question!???? As the conv-belt gets faster as does the plane the plane would be creating lift with the air that is being pushed back across the wings from the prop right? At some point waaaaaayyyyyyyyy faster than what any conv-belt could go the plane would have to take off?????? Or not 
!!!! That is a good one right there!!!!
! Man you have me visualizing the plane running on the belt getting faster and faster but not taking off, but then really taking off because of some force! Thanks for that one! JB

Yes it does. The speed of an airplane isn't determined by it's wheel speed since they free spin. The engines push it forward regardless of how fast the wheels or the converyor is going.

Apparently you guys weren't around for that legendary thread... it ended up locked.
It was assumed the plane was a jet, and my answer remains "no". This thread is off topic though...

i agree that the plane does take off because the force that propels the plane is independent of the wheels. no plane that i know of takes off using its wheels so i think that plane would take off no matter the speed of the conveyor and regardless whether the plane is jet or propeller powered...w/e...lol

and heres another plane question...
will a plane take off if it has a wind blowing in the same direction the plane is facing and matching the same speed as the plane at all times?

It is an impossible problem... so the plane won't take off.
