"separate and integrate" or "Orangutang method"

The Chaz · August 5th, 2011, 08:15 PM

My friend asked me to solve these (something about planetary motion or something...), but I'm too tired.
Anyone care to take a crack at it?
Cheers.

(p.s. The "Orangutang Method" is something I heard on MSE to refer to licentious use of "integration by separation")

Just got word that the second one (dr/dt) has an error... the right hand side is inverted.

So we should have

$\frac{dr}{dt}= \sqrt{F - \frac{k^2}{r^2} + \frac{2c}{r}}$

This one doesn't seem that bad.
(Well, it looks like some in my tables...)
