Destroy object if collision is strong enouf

Hi I am making a marble game and I was wondering how to make a script that could destroy an object if a marble is fast enouf. I hope you understand what I said… Thank you for answering.

You could try a if statement inside the collision:

function OnCollisionEnter(other:Collision){
   if(other.gameObject.tag =="box"){
      if(velocity>=fastenuf){
           Destroy(other.gameObject);
       }
       else {
           bouncingFunction();
       }
   }
}
