ActionScript 3.0 :: Circle Circle Frame Independant Collision Reaction?

Trying to do circle circle collisions via math which I'm really having trouble with. One circle (player) just moves from keyboard. The ball reacts to the player. All the code shown is in my players class and I passed in a reference to the ball.

On my enterframe I have:

Code:
var xmov1 = xSpeed;
var ymov1 = ySpeed;
var xmov2 = ballRef.xSpeed;
var ymov2 = ballRef.ySpeed;

[code]....

Perhaps I'll go with a box2d equivalent instead of trying out my own physics shenanigans.
