Hello,
Our team 2152 put together a VB program that would automatically calculate the velocity at which you needed to shoot to make the ball go a certain distance into a certain height. This program has three inputs height, distance you are away from the goal, and the angle at which you are shooting. Here is the .exe of the program we constructed that would do this you can download it from the exe below.
