Calculating max robot speed on a ramp

[grahamspam]

Hello everyone,

I am attempted to calculate the top speed of a robot on ramp,
given a specific gear ratio and ramp angle.

I have attached an excel spreadsheet with all the given information,
equations, and logical steps. The final numbers do not seem right
when the gear ratio is varied.

Thanks for your help!

I still need help on this inclined plane problem, if anyone has a few minutes. Thanks again!
