So this is the code , and the message i get is The call is ambiguous between the following methods or properties: UnityEngine.Vector2.operator +(UnityEngine.Vector2, UnityEngine.Vector2)' and UnityEngine.Vector3.operator +(UnityEngine.Vector3, UnityEngine.Vector3)’

using UnityEngine;
using System.Collections;

public class ball : MonoBehaviour {

private Paddle paddle;
private Vector3 paddleToBallVector;
private bool hasStared = false;
// Use this for initialization
void Start () {

paddle = GameObject.FindObjectOfType<Paddle>();
paddleToBallVector = this.transform.position - paddle.transform.position;
print (paddleToBallVector);

}

// Update is called once per frame
void Update () {
if (!hasStared) {
	this.transform.position = paddle.transform.position + paddleToBallVector;
}

	if (Input.GetMouseButtonDown(0)) {

	print ("Left mouse Clicked, Launch ball");
	hasStared = true;
	this.GetComponent<Rigidbody2D>().velocity = new Vector2 (3f, 7.5f);

}
}
void OnCollisionEnter2D (Collision2D collision){

	//Ball does not trigger sound when brick is destroyed
	//Not 100% sure why, possibliy because there isnt a brick
	Vector2 tweak = new Vector2 (Random.Range(0f,0.2f), Random.Range(0f,0.2f));
	if ( hasStared) {
	GetComponent<AudioSource>().Play();
	GetComponent<Rigidbody>().velocity += tweak;

	}

}
}

console error:
The call is ambiguous between the following methods or properties: UnityEngine.Vector2.operator +(UnityEngine.Vector2, UnityEngine.Vector2)' and UnityEngine.Vector3.operator +(UnityEngine.Vector3, UnityEngine.Vector3)’

In OnCollisionEnter2D() change this

GetComponent<Rigidbody>().velocity += tweak;

to this

GetComponent<Rigidbody2D>().velocity += tweak;

but instead may want to make the following changes to your class like so

using UnityEngine;
using System.Collections;

public class ball : MonoBehaviour
{
    private Paddle paddle;
    private Vector3 paddleToBallVector;

    private bool hasStared = false;
    
    private AudioSource audioSource;
    private Rigidbody2D rigidbody2D;

    // Use this for initialization
    void Start ()
    {
        paddle = GameObject.FindObjectOfType<Paddle>();
        paddleToBallVector = this.transform.position - paddle.transform.position;
        print (paddleToBallVector);
        
        audioSource = GetComponent<AudioSource>();
        rigidbody2D = GetComponent<Rigidbody2D>();
    }

    // Update is called once per frame
    void Update ()
    {
        if (!hasStared)
        {
            this.transform.position = paddle.transform.position + paddleToBallVector;
        }
        if (Input.GetMouseButtonDown(0))
        {
            print ("Left mouse Clicked, Launch ball");
            hasStared = true;
            rigidbody2D.velocity = new Vector2 (3f, 7.5f);
        }
    }

    void OnCollisionEnter2D (Collision2D collision)
    {
        //Ball does not trigger sound when brick is destroyed
        //Not 100% sure why, possibliy because there isnt a brick
        Vector2 tweak = new Vector2 (Random.Range(0f,0.2f), Random.Range(0f,0.2f));
        if ( hasStared)
        {
            audioSource.Play();
            rigidbody2D.velocity += tweak;
        }
    }
}
