That is too broad of a question to answer definitively. Bullet velocity can range from a few hundred feet per second to several thousand feet per second depending on the gun and the specifications of the cartridge.
Usually supersonic or mach 2 but this varies depending on the grain load the and the weight lead that is being shot.
The speed of a bullet shot out of a gun is dependent on the type of gun being fired and the specifications of the cartridge. Using a rifle, cartridges are propelled at a much faster rate, at around 4000 ft per second. A hand gun will send the bullet out at around 600 feet per second.
Yes, a bullet can be shot with no gun. A bullet does not need a lot of speed to kill someone. Say someone threw a bullet to the ground, it might bounce back up and hit you, thus causing you to die or be injured
No. That's why a bullet shot horizontally from a gun and a bullet dropped from the muzzle of the gun at the same time both hit the ground at the same time.
If the gun is stationary before the shot, then the momentum of the gun and the momentum of the bullet are equal and opposite after the shot.
Relative to the car, the bullet will act as if the gun is shot from a stationary position. Relative to the ground, it will go faster through the air.
Gun powder.
Affix the gun to a target. Load the bullet into a cartridge. Load the cartridge into a second gun. Aim carefully, squeeze the trigger. If you have done everything right, you will have shot the gun with a bullet.
Because that was the way it was loaded into the gun, shot charge, bullet charge, shot charge, bullet charge. If you load it that way, it will shoot that way.
Yes.

Going "like a shot" means "as straight and as fast as a bullet shot from a gun."
The mass of a bullet is nowhere near the mass of a gun. A bullet weighs at most a few hundred grains. Most guns weigh at least a couple of pounds, some weigh several pounds (talking about handguns and rifles).
If the bullet were shot perfectly vertically in a vacuum, it would reach its maximum altitude, then fall at a velocity of 32 ft/sec/sec. The terminal velocity would depend upon the altitude reached by the bullet, which in turn depends upon the caliber and load of bullet shot.
