Collision detection of a ball with an arc

Question

I am making a simple game in which i have a ball and an arc revolving around the center. When user touches the screen the ball moves in the direction of pointer and hits the arc

Answer 1

If it is possible for you to find the segments which make up the arc, then you could use the Intersector class to check if the circle collides with each segment. I don't know how you're making your arc so I don't know if you can get the segments or not.
