What go's up must come down..
Gravitational force has a velocity of 9.8m/sec..
So whatever goes down, always comes down with accelerating speed.It is pausible this actually happened to strike and kill this girl..
Drop a book on your hand a foot off the ground..
Drop the same book on your hand at 2ft 3ft 4ft etc..
It will hit with more force every single time..
Drop it from 100 ft on your hand, and it will be crushed if not amputated..
