How to make soccer ball spin according to its velocity in 2D top down game

Hey all, so I've been having some troubles making a soccer ball spin according to its velocity. I'm making a 2D top-down game where the character and the ball have colliders. The ball has a rigidbody 2d as well so that it moves when colliding, but it just goes on forever until it runs into another collider. The problem is, though, is that im having a lot of trouble making the animations in in animator controller work and look good. I have a top roll, bottom roll, left roll, and right roll. I don't know if i should make diagonal rolls too. What should i do to A: make it slow down to a stop (like friction) and B: make the animations look good. Thank you all a ton, and sorry if i worded this weirdly / its confusing.
