The kid may not realize that he was not actually hit by the object. He knows that something hit him, and he went flying.

When we were studying momentum in physics, we calculated an inelastic collision of a car and a bug. How fast would the bug need to be moving to bring the car to a stop? It gives you some perspective on what would really happen. At 14, the kid probably just doesn't know. At least some news stories asked the right questions.
