Hi Philip, You can find an old article of mine on 2D vectors at... <http://nonlinear.openspark.com/alpha/articles//vectorarticle.txt> ... along with a demo movie at: <http://nonlinear.openspark.com/tips/geometry/2Dvectors/> These should help you with the movement of the ball and collision management. As for determining which straight-line path will form a given angle with a given curve from a given point, the complexity of the mathematics will depend on the complexity of the curve. Are you using circles, ellipses, parabolas,... or are you using a more complex formula to define the curves?
