Re: think about this...
This thread is moving in a brilliant direction I never foresaw.
And the beautiful part is, people are still chiming in with the wrong answer to the OP. [img]/images/graemlins/grin.gif[/img] |

Or maybe the conveyor ramps up to infinite speed and the universe collapses? [/ QUOTE ] You can use kevyk's work to figure out the speed of the wheels and conveyor... how do I say this without giving it away... no, that's all. However, this still has nothing to do with the plane's ability to take off, given the parameters here. |

[ QUOTE ] gravity lol [/ QUOTE ] so good. how is this that complicated though? the plane is not going to take off. the conveyor will push it backwards with the same force that the wheels push it forward, and the plane will stay stationary relative to the ground. and LMAO to the person who thought the propellors were the source of the air that blows over the wings. AWESOME. i got a 1 on the ap C physics test, so maybe I am a physics idiot. but that was for lack of effort not intellegince. [/ QUOTE ] I love when people say this. It's like a foolproof excuse for being afraid of trying and failing. |

Re: think about this...
Yeah, except I realized right after I posted that I made a big mistake...
Namely, the speed of the wheel where it touches the ground is zero if there is no slipping. Duh...in that case you've got no treadmill-runway at all. In any case it doesn't matter. The moving runway doesn't exert any force on the plane, so the engines will accelerate it to normal airspeed and it will take off. The wheels will just spin faster than they would otherwise. |

I got a 5 on BC calc, im not just making it up. i have tons of evidence to say that im a smart person.
and yes, intelligence was spelled incorrectly on purpose. |

ok, I think I'm still missing some stuff, but I tried to be as thorough as possible. I demand a lot of partial credit for showing formulas

opposite direction of the plane [/ QUOTE ] Define "opposite" if the plane isn't moving. |
