    well..

    Ball(i).x = Ball(i).x + Sin(Ball(i).Angle) * 5
    Ball(i).y = Ball(i).y + Cos(Ball(i).Angle) * 5

    First of all change *5 to *speed so you can increase difficulty.
    Secondly, it MAY be a radians/degrees problem.

    Try this:

    Ball(i).x = Ball(i).x + Sin(Ball(i).Angle*3.14/180) * ball(i).speed
    Ball(i).y = Ball(i).y + Cos(Ball(i).Angle*3.14/180) * ball(i).speed

    *Pi/180 converts degrees to radians, to change back to *180/Pi

    I'm pretty sure this is your problem.
    Don't pay attention to this signature, it's contradictory.
