add force to object that has 2 different rigid bodies

Hi, I have a question and it is important for me to know what could be the approaches to it, because this is always a problem for me. I am trying to make a clone of "push'em all" mobile game. I have a player object that has a rigidbody and it has several game objects on it. And one game object "movingpusher" has also its own rigidbody. Now, if my enemies get in trigger with player object, they push the player forward but, I just use "AddForce" to player object's rigidbody and the result is like at the attached photo.

And this is the code part

 private void Awake()
         {
             EnemyController.PushPlayer += GetDamage;
             PlayerRigid = gameObject.GetComponent<Rigidbody>();
         }
       
         private void GetDamage()
         {
             Debug.Log("TakingDamage");
             gettingDamage = true;
             PlayerRigid.AddForce(StablePusher.forward * 50);
             PlayerRigid.velocity = transform.TransformDirection(0, 0, 5);
         }

Now, I know I can also use AddForce for the MovingPusher's rigidbody, but I am totally sure this is not a good way, and I will be appreciated if you could share your ideas :)
