that ball flying with high speed and hit behind her head. If something heavily hit behind of your head you will pass out or even die due to skull fracture, that is why when people drive motorcycles they wear helmets. I'm sure she will have problems later on when she gets home that day, the worst case is she will throw up alot and that is direct effect. With a speed like that, the ball hit really hard. Avoid the head at all cost.
