Hey, is there a way to have an object constantly keeping up with a mouse collision, as the mouse seems to fast for the update()

I've tried changing the mouse's rigid-body body type as well as using fixed/late update();

I'm trying to move a line controlled by the mouse to push an object, but as i get a little to fast it goes through the object as if update isn't running enough times per second to keep up.

     void FixedUpdate()
     {
 
         if (Input.GetButton("Fire2"))
         {
             transform.position = newPos + (mouse.transform.position - oldPos);
         } else
         {
             oldPos = mouse.transform.position;
             newPos = transform.position;
         }
          lineDrag();
     }
