Speaking of CSI and guns . There was this one episode where a guy shot a pistol into the air from a balcony , the bullet flew up , and due to gravity it fell back down killing a woman lying on the grass having a pic-a-nic , is that even possible?
Depends on weight of the round and muzzle velocity.
take into account that bullets are fired at very high speeds and are aerodynamic to some extent. That means that in a time interval it will climb higher the faster it goes.
Since the bullet de-accelerates over time, the higher it climbs over time means that it will reach a good height before gravity nullifies the bullet's speed.
Take into account that the bullet will accelerate around 10 m/s each second it falls.
A bullet normally only needs 60-70 m/s to be able to penetrate skin.
A friend of mine has a bullet hole in his car. It was probably someone shooting at the sky during New Year's Eve. Pierced trough the roof and the seat.
