As such speeds, wouldn't air resistance come into play?
Honestly, I'm doing this for fun without expecting accuracy, but I'd love to get as accurate as possible.
Ether, if you happen to be around, I'd love to get your input on this problem, since you know pretty much everything.

Using the viscosity of the air, I'm able to estimate the resistive force on the sphere (since it is a sphere, it makes this calculation much simpler instead of using the drag calculations.. which is okay, but i just prefer this one).. at 10m/s you will encounter significant drag.
Here's an Octave/Matlab script that does the estimation (working with iterative solution... no calculus involvement yet.. which seemed rather difficult to do)
