So how did you get the TeX looking formulas in your post?

Thanks - the T_{up} = T_{down} was counter to my physical intuition, so I was suspicious. Thanks for your time. This was not an assignment.

I don't think the file uploaded, so here's a copy: http://caccmath.cacc.cc.al.us/air-resist.pdf

Here are the results for linear air resistance. The quadratic resistance results are being written up now. I hope I did the attachment correctly.

Let me finish writing it up and then I'll submit it in pdf form.

I've solved the problem and would like to see if someone gets the same results.

My question deals with times of flight under a linear model of air resistance. Let me describe the problem. Up problem: v' = -g - kv, x(0) = 0, v(0) = v_0 Down problem: v' = -g + kv, x(0) = h, v(0) = 0 Define T_{up} and h (max. height) by the Up problem: x(T_{up}) = h, v(T_{up}) = 0...
