Falling, and not tumbling end over end, the bullet will accelerate (due to gravity) at 32 ft per second- per second- until it reaches the terminal velocity- limited by air resistance- around 300 mph. If tumbling end over end, more air resistance, less speed- about 225 mps MAXIMUM.
No the full speed of the bullet would be when it is fired, once the bullet travels along the barrel and exits the muzzle it is already slowing
It is called Free Fall.
a skydiver falling is affected by air friction or he would fall straight down in an instant
The net force on a 7 pound object that is falling (accelerating down) is 7 pounds. If it is not falling or moving at a constant speed, it is zero.
Yes. It's possible and it has happened several times for real.
They depends on the weather, the aiming degree. For instance if you're shooting upwards, the bullet will slow down until it starts falling down, which will increase the speed.
it slows down their speed
Yes. It has happened before.
No the full speed of the bullet would be when it is fired, once the bullet travels along the barrel and exits the muzzle it is already slowing
Car crash, falling from 3 or higher stories building, slide down, hit by bullet,
It is called Free Fall.
I assume what you are asking is "if you shoot a gun straight up in the air will the bullet come down at the point where it was shot from". The answer to that question is NO, the rotation of the earth will move the point of impact.
Logical. When you plummet from an extremely tall building, you're falling straight to your death.

Is there any wind? What's the elevation and barometric pressure (air density)? What's the coefficient of friction on the bullet's cross-section? How many rotations per minute is the bullet turning? Will it flip and fall point down at the top, or sideways, or tail-first? If you're looking for a "real world" answer, there's a LOT of information missing, a LOT of variables... If you're thinking in a vacuum, no wind, basically a physics class problem, it'll be about 50 seconds, and hit a peak altitude of about 3062.5 meters before falling.
The sound may or may not "come first" when a bullet is fired. Particularly if we make the decision after collecting data from down range. The muzzle velocity of some firearms does notexceed the speed of sound. In those cases, the sound will reach a "target" down range before the bullet does. But the muzzle velocity of other firearms does exceed the speed of sound, and in those cases, the bullet will arrive down range before the sound does.
The velocity of a bullet coming down from altitude is the terminal velocity of the bullet fired. Since not all bullets are equal in mass, it would depend on the grain (weight) of the bullet fired, the caliber of the bullet, and the charge behind the bullet (which would determine the highest possible altitude it could reach). To determine the terminal velocity of any bullet, you must first know these variables and plug in those variables to the equation below: That is, * Vt = terminal velocity * m= mass of the bullet * g = gravitational acceleration * Cd = drag coefficient (wind resistance applied to the bullet as it falls) * ? = denisty of the medium through which the bullet is falling (the atmosphere) * A = projected area of the bullet (which can get complicated due to the shape of the ball). Essentially, the following is true: any bullet fired straight upward is not only potentially but very likely as deadly to anyone it might strike when it lands as if that same bullet were fired directly at that person.
