springjoint2d - how to reset without starting new scene

Maybe you could use: SpringJoint2D.dampingRatio

The spring will oscillate with a certain frequency as it attempts to reestablish the desired distance between the objects. The higher the damping ratio, the quicker the oscillation will die down to zero.

Maybe you could go with something like this:

 using UnityEngine;
 using System.Collections;
 
 public class ResetSlingShot : MonoBehaviour {
 
     [SerializeField]
     int ResetDelayTime = 5;
     [SerializeField]
     float dampingRationValue = 100.0f;
 
     bool SlingShot_isTriggered;
 
     SpringJoint2D mySpring;
 
     //-------------------------------------------------------------------
     void Start()
     {
         mySpring.GetComponent<SpringJoint2D>();
     }
 
     //-------------------------------------------------------------------
     void Update()
     {
         if (SlingShot_isTriggered == true)
         {
             StartCoroutine(ResetTimer());
             mySpring.dampingRatio = dampingRationValue;
         }
     }
 
     //-------------------------------------------------------------------
     IEnumerator ResetTimer()
     {
         yield return new WaitForSeconds(ResetDelayTime);
     }
 }

i want to know how to get the spring back after it gets deleted when you set the kinematic

GetComponent().isKinematic = false;

how can i get it back without restarting the scene?
