How would i create a rubber band effect in 2D physics?
So i have 2 points and an elastic string between those points
If i drop a ball onto the string, it deforms, absorbs the momentum and flicks the ball back

A bit like this;

Personally, I wouldn't consider the rubber band to be a physics object. I would draw it manually then when you release it, you calculate the direction and magnitude of the force to exert and apply that to the physics object you are launching.

Scraggle has a good idea there
The below will give you the up and down concept add some physics and ofcourse modify to get the sideway effect
and it may be what you need. My math failing me atm I cant remember what to add to give the side way effect to the
curve

Here you go.
It's very rough and ready and you could do a lot to improve it but it is a workable "proof of concept"

No media required. Just click on the red 'ball' and drag it. Then release to launch it.
