Crossing Soccer ball system Help

Hello, I'm doing a crossing system for a soccer game, and i managed to cross a ball to a target. The current code ads a curve to the ball, but it only works if the crossSpeed variable is 5, and if the player y axis is at a certain height, if i change the player y axis i need to adjust the drag and angular drag of the ball for it to work correctly. I took this formula from this unity question: https://answers.unity.com/questions/384515/addforce-to-go-a-specific-distance-and-height.html?sort=votes vWSpeed, are supposed to be the offset for the ball to go to the left, for it to then get curve from the AddCurveToBall function. Can anyone help make this code work for multiple cross speeds?

 private void FixedUpdate()
     {
         //if we are crossing the ball add curve to it
         if(addCurveToBall)
             AddCurveToBall();
     }
 
     //this will cross the ball
     public void StartCrossBall()
     {
 
         //get the direction from the ball to the player
         Vector3 dir = playerHead.transform.position - transform.position;
 
         //normalize the direction
         dir.Normalize();
 
         //balistic trajectory
         float g = Physics.gravity.magnitude; // get the gravity value
         float vSpeed = Mathf.Sqrt(2 * g * playerHead.transform.position.y + 2f); // calculate the vertical speed
 
         //balistic trajectory
         float gW = Physics.gravity.magnitude; // i use the gravity value for the curve
         float vWSpeed = Mathf.Sqrt(2 * g * playerHead.transform.position.y + 2f); // calculate the curve speed 
 
         float totalTime = 2 * crossSpeed / g; // calculate the total time
 
         float hSpeed = Vector3.Distance(transform.position, playerHead.transform.position) / totalTime; // calculate the horizontal speed
         rb.velocity = dir * hSpeed;
         rb.velocity += new Vector3(0, vSpeed + yOffset, vWSpeed + xOffset); // launch the projectile! 
         //rb.velocity += new Vector3(hSpeed, vSpeed, dir.z + 0.5f); // launch the projectile! 
 
         addCurveToBall = true;
     }
 
    
 
     void AddCurveToBall()
     {
         //rb.AddForce(Physics.gravity * rb.mass);
         rb.AddForce(new Vector3(0,0,Physics.gravity.y) * rb.mass);
     }
 
     private void OnCollisionEnter(Collision collision)
     {
         addCurveToBall = false;
         ResetRigidBodyPhysics();
     }
