You don't need physics - just a simple if/else. Assuming you're talking about vertical and horizontal walls (like those of the containing box).

Give it a thought yourself and you'll probably find it's easier than you expect. You're already calculating the ball's "angle" using X,Y components so consider what happens to them if you have, say, a velocity {x=1, y=2} at the time when the ball encounters a horizontal wall...
