[Solved] Speed up Ball - Ballbreaker Game

Unity Engine
1

Hi,
I m making a simple ball breaker game and I use the code below to handle ball launch and collisions . Whole procedure uses Vector2 for launch and for angle change as well. My goal is to speed up ball by time. I know I can use coroutines but my issue is how to handle speed when movement is made with vector2 .

Ball scripts contains bellow code ;

Launch Ball

    public void ShootCannonsOnClick()
    {
        if (Input.GetMouseButtonDown(0))
        {
            GetComponent<Rigidbody2D>().velocity = new Vector2(XLanch, YLanch);
            //Myrigidbody2D.velocity = transform.forward * BallSpeed;
            GameStarted = true;


        }

    }

Change Angle when collide;

    private void OnCollisionEnter2D(Collision2D collision)
    {
        Vector2 velocityTweek = new Vector2(UnityEngine.Random.Range(0.0f, randomFactor), UnityEngine.Random.Range(0.0f, randomFactor));
        if (GameStarted)
        {
            AudioClip clip = Ballsounds[UnityEngine.Random.Range(0, Ballsounds.Length)];
            MyAudioSource.PlayOneShot(clip);
            Myrigidbody2D.velocity = Myrigidbody2D.velocity + velocityTweek;
        }

    }

I think I solved after days.Currently works when space is pressed. In case anyone else is wondering ;

    public void changeSpeed()
    {
        if(Input.GetKeyDown(KeyCode.Space))
        {
            Myrigidbody2D.AddForce(Myrigidbody2D.velocity.normalized * BallSpeed);
        }

    }
