t$$anonymous$$ng.gameObject.AddComponent(); you had it, but your problem is going to be that the rigidbody is added when the wall is $$anonymous$$t, w$$anonymous$$ch means no force is added to your wall. The solution is to cast a ray in the rocks trajectory ('t$$anonymous$$ng.rigidbody.velocity.normalized') and if the ray $$anonymous$$ts the wall, add the rigidbody and its properties

use gameObject.AddComponent();

Just be sure to check to make sure it has a rigidbody first. Though I'm not sure if adding a rigidbody as soon as the rock $$anonymous$$ts the wall is going to be enough time for physics to respond. I could be wrong - only one way to find out.
