Ok, some one give me a question, if you stump me then I will CP you, However, If I get that question right I would request CP from you instead. Clear? GO! if you highjack this thread you owe me 20 CP. that is all.

Originally posted by SM19A plane sits on a large conveyor belt (wide enough to accomodate the plane's wheelbase) that is programmed to run backward at the same speed that the plane moves forward. Can the plane take off?
There is a variation on this riddle that says that the conveyor belt matches the speed of the plane. It doesn’t matter… the plane still takes off. The conveyor belt could be going 5 times as fast as the plane, and the plane would still take off.

It's not the net speed which matters, it's just the speed of the plane, and when it reaches the lift off speed on the conveyor belt it'll still take off because of the thrust generated by the engines as the plane is still essentially moving forward, the net velocity doesn't matter, only the plane velocity.sigpic

The solution is confusing.HEAR ME ROAR!

The solution is confusing.

You get a beach hut! (Natural) Log cabin + c That's an olllld one :p To a mathemagician, obviously/
If I were sin squared and you were cos squared, then why would we be the perfect couple?Last edited by muse; 03312006, 11:43 AM.sigpic

STUMPER:
Solve the following differential equation using a Laplace transformation:
Code:dy  + y = x^2  d(x2) dx

I wanted a CP outta that!

That's correct... planes manage airflight due to lift of the air pressure... which is from the air moving faster over the wings than it is moving under the wings. So unless the conveyer belt is also moving all the air with it, I don't buy this explaination.
It makes me feel a little better that you agree with me.
A little.HEAR ME ROAR!
