Save the position on your start function :

public class MyBall : MonoBehaviour
{
     private Vector3 original_pos;

     void Start()
     {
           original_pos = transform.position;
     }

     public void reset_position()
     {
           transform.position = original_pos;
     }
}

then add a script and a collider to the terrain :

public class MyRespawner : MonoBehaviour
{
     void OnCollisionEnter(Collision coll)
     {
           MyBall player;

           if (coll.gameObject.tag == "player")
           {
                 player  = coll.gameObject.getComponent<MyBall>();
                 player.reset_position();
           }
     }
}

You shouldn’t use a terrain but a plane with a Trigger Collider (and change OnCollisionEnter by OnTriggerEnter)
