Drag Player Object using Physics 2D

I want to drag player object to throw coming obstacles in the way. For this purpose, I require to hold the player object and using it, I require to hit upcoming obstacles in the gameplay.

Basically currently I am working on this type of gameplay:
Rise Up Game - Level 40+ 7851 High Score!!!

At present I am trying to hit obstacles using this setup:

  void Update()
     {    
         Vector2 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
         Rigidbody2D.position = mousePos;    
     }

Here are the inspector settings:

Still, the player hitting is jerky or not smooth. Multiple times obstacles get fixed within player object.

So how to make this hitting proper?
