Re: Projectile Motion

Doing the math can certainly help (and is very educational)... but personally, I would rather set it up with trial and error. Get your robot set up so you can easily change the shooter speed (using a potentiometer on the OI, for example), and feed in balls until you find the right speed for a given distance. Do this for several different distances, plot the results, and find a line of best fit (linear, quadratic, whatever gives the best results).
