Jumping spring (pass a rigidbody velocity value from another script)

Hello, I am writing a script for a jumping spring for a player that is supposed to make the player jump at different speeds for each spring. The issue is that I have two springs in the same scene and they always have the same speed value no matter how I change both.

the script is as following:

 public class Spring : MonoBehaviour
 {
 
     public GameObject player;
     private Rigidbody2D RB;
     public Vector2 Speed;
     private Animator anim;
     private AudioSource audi;
     private bool JumpPlayer;
     private bool JumpOnce;
 
     // Start is called before the first frame update
     void Start()
     {
         RB = player.GetComponent<Rigidbody2D>();
         anim = GetComponent<Animator>(); 
         audi = GetComponent<AudioSource>();
        
       
 
     }
     void Update()
     {
         CheckIfPushed();
         if (JumpPlayer && !JumpOnce)
         {
             StartCoroutine("PushJump");
         }
         else if (!JumpPlayer)
         {
             JumpOnce = false;
             StopCoroutine("PushJump");
             anim.SetBool("Push", false);
         }
     }
 
     // Update is called once per frame
     
    
     IEnumerator PushJump()
     {
 
         JumpOnce = true; 
         yield return new WaitForSeconds(0.1f);
         anim.SetBool("Push", true);
         RB.velocity = new Vector2 (Speed.x , Speed.y);
         audi.Play();
       
       
     }
     void CheckIfPushed()
     {
         if (GameBrain.isPushed)
         {
             JumpPlayer = true;
         }
         else if (!GameBrain.isPushed)
         {
             JumpPlayer = false;
         }
     }
     
 }
