Projectile Motion

[commonsense]

Hey does anyone have a good algorithm for finding the velocity needed for the ball to go a certain distance and height. We have been working on it, but it has been pretty drab, and one of our programmers walked out on us because of it (of course he was pretty tired and needed food.) Or if you already have it programmed in LABview that's what we are using. This would be amazing cause it has been really nerve racking to try and do the physics (it's been months since I have had to do this work.) Thanks
