That is exactly right. :hi5:
The guy with the pilot friend needs to remind his friend that he is only a pilot and NOT an engineer! If he is an engineer, he's not a smart one. My dad IS an engineer and I argued with him for 30 minutes before I got him to agree with me. (I guess I'm the rocket scientist?)
The guy that said the tires would burn up is overanalyzing too. Even if you aren't overanalyzing, there are planes that take off well under 200mph and there are tires that are rated well over twice that. This is a really simple problem and the plane wont stay still. The problem is written to make you believe that it would. Did you read my examples with the rocket above? I think I explained really well why the plane would fly. I'm really disappointed in the people who think it won't.
For the THIRD TIME, I'll repaste the problem so you can read it...
"A plane is standing on runway that can move (some sort of band conveyer). The plane moves in one direction, while the conveyer moves in the opposite direction. This conveyer has a control system that tracks the plane speed and tunes the speed of the conveyer to be exactly the same (but in opposite direction).
The question is:
Will the plane take off or not? Will it be able to run up and take off?"
NOWHERE does the problem say that the plane will stay in one place! The problem asks you to decide if it will stay in one place!!
Once again... I'm very disapointed in the people who think the plane won't fly. And to think, you are the same guys I ask for help to fix my car. :slap:
