How to change the force for seconds using a Coroutine?

Question

2D C#

I have a simple and probably very stupid question, which is why I apologize for any possible littering of the forum.

How to make the object's ("Player") forceFly increase by 1000 when it hit the object: "BrownWorm" (in OnCollisionEnter2D), for 5 seconds, then return to normal?

My main problem is the lack of assigned value to fireFly, because I want to specify it in the inspector.

I know that to return after 5 seconds I should add IEnumerator and yield, but I do not know know how to start this power change.

I would also be grateful if someone in this example would explain how it works,

My script:

         using System.Collections;
         using System.Collections.Generic;
          using UnityEngine;
 
 public class PlayerBehaviour : MonoBehaviour {
 
     public Transform mesh;
     public float forceFly;
     private Animator animatorPlayer;
 
     private float currentTimeToAnim;
     private bool inAnim;
 
     // Use this for initialization
     void Start () {
         animatorPlayer = mesh.GetComponent<Animator>();
 
         this.gameObject.GetComponent<Rigidbody> ();
     }
     
     // Update is called once per frame
     void Update () {
 
         if (Input.GetMouseButtonDown (0)) {
             
             inAnim = true;
 
             GetComponent<Rigidbody2D> ().velocity = Vector2.zero;
             GetComponent<Rigidbody2D> ().AddForce (new Vector2 (0, -1) * forceFly);
 
         }
 
         if (inAnim) {
             currentTimeToAnim += Time.deltaTime;
 
             if (currentTimeToAnim > 0.4f) {
                 currentTimeToAnim = 0;
                 inAnim = false;
 
             }
         }
 
         animatorPlayer.SetBool ("callFly", inAnim);
     }
         void OnCollisionEnter2D(Collision2D coll){
         if (coll.gameObject.tag == ("Enemy"))
 
                 Destroy (gameObject);
         }
 
 }

Problem solved by myself. I added some variables false, true and everything works.

Simple!!

      public float forceFlyAdd;
          public bool isFaster;
      
          void OnCollisionEnter2D(Collision2D coll){
              if (coll.gameObject.tag == ("Player"))
                  isFaster = true;
                  Debug.Log ("Speed Powerup");
                  Destroy (gameObject);
                  PlayerBehaviour theSpeed = coll.gameObject.GetComponent<PlayerBehaviour> ();
                  float temp = theSpeed.forceFly;
                  theSpeed.forceFly = forceFlyAdd;
                  StartCoroutine ("WaitTime", theSpeed);
                  theSpeed.forceFly = temp;
              }
      
      
          public IEnumerator WaitTime(PlayerBehaviour playerForceFly) {
              yield return new WaitForSeconds (5);
              isFaster = false;
          }
      }

I made the changes near startCoroutine!!
