I am trying to find the new position of a circle after it collides with a line, best explained by looking at this explanatory image.

I've got

• Point A: Position of the circle [center of blue circle, start of red line]

• Point B: New position of the circle [end of red line]

• Radius R: Radius of the circle

• Point LS: Start of the wall [black line]

• Point LE: End of the wall [black line]

I would like to calculate the new position of the circle after it collides with the line [Position of the orange circle].
