Maybe I just worked this out too quickly but, check my math here:
Assuming you're comfortable with approximating instantaneous acceleration with
\dot{\omega}=\frac{\omega - \omega_o}{\Delta t}
then:
G^2 = 1 + \left( \frac{\omega^2 R}{g}\right)^2 + \left( \frac{\dot{\omega...
You might want to try posting questions like this in the Homework Help Forum. Anyway:
8\% = \frac 8 {100} = \frac{\rm rise}{\rm run} = \frac{800}{\rm run}
Solve for the run.
Well, it's been like forever and a day since I did problems like this, but I think it goes something like this:
154x + 260y = 4
260 = (1)*154 + 106
154 = (1)*106 + 48
106 = (2)*48 + 10
48 = (4)*10 + 8
10 = (1)*8 + 2
8 = (4)*2
4 = 2*2 = 2*(10-8) = 2*(10-(48-4*10))
=...
