I don't know if this is the right Topic, but I think it is, it has something to do with science.
I was curious if anyone knows how fast the propellers of an Apache helicopter go, like RPM's a minute or whatever, and how long are they, I guess if you could tell me the total (wingspan?) that would be okay.
I asked my parents this and they said just write on your homework, "Really damn fast and pretty damn big.", so if you think the same thing I am going to tell you the samething I told them.
This is not a homework problem! I am just curious, I had an idea. If this is not good enough for you, then I will come up with an excuse. I am coming up with a very hard Calculus problem that I am trying to stump my friend with. How's that?
