Change animation at runtime with Mecanim

Dear Community,

I have a little 2D-Ball GameObject. I want it to be instantiated, and its transform.position to be animated, whenever I click the mouse button. The balls starting position is the position where I clicked. Then I want it to pass another Vector2 and end at a t$$anonymous$$rd. All Vector2 positions are different every time I play the animation. How do I access the balls animation every time that I want, but set the keyframes to different values?

Or should I not use animation at all? Should I use the update function with Vector3.movetowards or Vector3.Lerp???

Thank you for your support!
