waitForSeconds not working C#

Hey everyone I research a bunch of time on the waitforseconds method. It is not working at all. I looked and looked on the forms for answers and nothing seems to work. I want the game to pause before the game really starts, but the game seems to just go without anything happening.

Here is the Code:

using UnityEngine;
using System.Collections;

public class ballControl : MonoBehaviour {

    public float ballSpeed = 100;

	// Use this for initialization
	void Start() {
        StartCoroutine(Wait());
        GoBall();
	}

    void GoBall()
    {
       
        float randomNumber = Random.Range(0, 2f); // needs to be 2
        if (randomNumber <= 0.5)
        {
            rigidbody2D.AddForce(new Vector2(ballSpeed, 10));
            Debug.Log("shoot Right");
        }
        else
        {
            rigidbody2D.AddForce(new Vector2(-ballSpeed, -10));
            Debug.Log("shoot Left");
        }
    }
	
	// called once per frame automactally 
	void OnCollisionEnter2D (Collision2D collInfo) {
        if (collInfo.collider.tag == "Player")
        {
            Debug.Log("ITS WORKING!");
            rigidbody2D.velocity = new Vector2(rigidbody2D.velocity.x,   rigidbody2D.velocity.y/2 + collInfo.collider.rigidbody2D.velocity.y/3 );	
        }
	
	}

    // This function waits 5 Seconds before starting the game

    IEnumerator Wait() 
    {
        print(Time.time);
        yield return new WaitForSeconds(2);
    }
}

The coroutine executes separatelly from the main thread so GoBall() will execute inmediatelly after StartCoroutine.

If you want it to execute after those seconds, put the call to GoBall inside the coroutine:

using UnityEngine;
using System.Collections;
 
public class ballControl : MonoBehaviour {
 
    public float ballSpeed = 100;
 
    // Use this for initialization
    void Start() {
        StartCoroutine(Wait());
    }
 
    void GoBall()
    {
 
        float randomNumber = Random.Range(0, 2f); // needs to be 2
        if (randomNumber <= 0.5)
        {
            rigidbody2D.AddForce(new Vector2(ballSpeed, 10));
            Debug.Log("shoot Right");
        }
        else
        {
            rigidbody2D.AddForce(new Vector2(-ballSpeed, -10));
            Debug.Log("shoot Left");
        }
    }
 
    // called once per frame automactally 
    void OnCollisionEnter2D (Collision2D collInfo) {
        if (collInfo.collider.tag == "Player")
        {
            Debug.Log("ITS WORKING!");
            rigidbody2D.velocity = new Vector2(rigidbody2D.velocity.x,   rigidbody2D.velocity.y/2 + collInfo.collider.rigidbody2D.velocity.y/3 );   
        }
 
    }
 
    // This function waits 5 Seconds before starting the game
 
    IEnumerator Wait() 
    {
        print(Time.time);
        yield return new WaitForSeconds(2);
        GoBall();
    }
}
