Hit ball with racket

The post is old but If somebody will stuck on this: The only one way to make it working nice is to make collision detection and changing velocity of the ball without rigidbody on the racket.

So, how i made it:

1) create empty prefab (name it RacketController for example) and give him box collider with a trigger and rigidbody with cinematic, like a child of this object i add Racket with only box collider. (I need parent cose i must to change the child visible or not for type of controller tracker or joystick)

2) Add a script to RacketController that change Rigidbody position (important that it is rigidbody) to position of my right controller

3) Add checking velocity of the rigidbody and saving it to variable

4) Create a ball with a rigidbody and sphere collider

5) Create a script and add it to the ball where i cheeking the collision and use such formula

 direction = Vector3.Reflect(lastFrameVelocity.normalized, collision.contacts[0].normal);
 this.GetComponent<Rigidbody>().velocity = direction * speed;

where lastFrameVelocity is the velocity of the ball on starting collision and collision is the object that ball is touching. And after i just add new velocity to the object. And i the object name is Racket for example i get the velocity from RacketController and multiply it with the ball velocity.

 float addForce = RacketController.GetComponent<TrackerFollow>().RacketVelocity.magnitude;
 speed += addForce;

And i remove physics material from the ball to make all work done by script.

The final result not best but now the ball not crossing the object through. There need some working with a script to make force on ball more realistic but it work.

Hope for someone this post will be useful. And this is result on video: https://youtu.be/F2_PllPlV4M

The video link does not work anymore. Can you please post again? I am wondering how you check the velocity of a Kinematic Rigidbody in step 3 above. Do you calculate it based on transform.position?
