Why just-out-of-college Calc Teachers are Awesome

Postby Aubron » Wed Oct 01, 2008 1:20 pm UTC

Our AP Calc BC work yesterday was based entirely around variations of the following question.

Suppose that There is a cliff, near infinitely high, spawning the relative height from earth's surface of the entire observable universe. For the sake of simplicity, let us assume that... somehow... the gravity is uniform throughout. A certain man with a hat, with an evil tendency, drops a cat off of said cliff, giving the cat no initial velocity. The cat goes, "Mrowl" and then immediately falls. What general equation would tell you how far down the cat is after 3 seconds?

Also, citing the work of art that this problem comes from gives 5 extra points on your quiz. Go.

I'm going to do a bit of nerd sniping here and say you did not account for the Lorenz Transformation.

I feel it's getting a bit complex for a three second timespan.

I did later take a stab at using a R-K, but with little noticeable difference.

This is the sole reason I'm interested in getting into education.

I can't make heads or tails of the grammar in that phrase.

:D Thats Awesome.

Sitting here in the library, wearing my xkcd shirt, I feel so proud. Proud enough that I would wear a black hat.

I think it's supposed to be 'spanning.' It'd take a remarkably prurient diety to spawn that kind of distance.

Think about the biggest cliff ever. It's bigger than that.

No, it's not a logical contradiction. Get used to it.
What they (mathematicians) define as interesting depends on their particular field of study; mathematical anaylsts find pain and extreme confusion interesting, whereas geometers are interested in beauty.

Yeah, the OP simply misread (or mistyped) spanning as spawning.
Unless stated otherwise, I do not care whether a statement, by itself, constitutes a persuasive political argument. I care whether it's true.

And I'm going to point out that, unless g is enormous, that's not going to start mattering yet after only 3 seconds. (In other words, the height of the cliff was actually irrelevant to the question.)

Also, wouldn't relativity be all kinds of messed up by a gigantic uniform gravitational field? Pretty sure this problem is assuming a Newtonian universe.

Which work of art? Was there an xkcd comic involving a cat?

A: Yes, incorrectly copied and posted. SPANNING.

B: The height mattered for nothing except for novelty that we were equating an xkcd.
