An astronaut on the moon fires a rifle, making sure that the barrel is exactly horizontal to the
surface. At the exact moment the bullet exits the barrel, a second astronaut drops a bullet from
the same height as the barrel.
The dropped bullet hits the ground first because it hasn't been fired and thus has greater mass.
Both bullets hit the ground at exactly the same time.
The fired bullet hits the ground first.
The dropped bullet hits the ground first.
