We're going to ignore air resistance.
Time the bullet spends on the way up = 245/9.8 seconds
Time it spends on the way down to the same elevation as the muzzle = another 245/9.8 seconds
Total time to return to the elevation of the muzzle = (2 x 245 / 9.8) = 50 seconds.
From there, we don't know how high the muzzle of the gun is above the ground, so
we can't calculate the duration of the extra little bit until the bullet hits the ground.
50 seconds
No- or minimal at best. Acceleration of the bullet comes from gas expanding inside the barrel, pushing the bullet. Once it leaves the barrel, (or within a VERY short distance) gas is no longer pushing, and acceleration stops, and bullet begins to slow from air resistance.
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
Bullet trajectory is the path the bullet travels once it leaves the barrel. Bullets travel on a long arch and cross the line of sight twice. Once shortly after leaving the barrel and once again on target assuming the sights are properly zeroed. This is the trajectory of the bullet. Bullet velocity is the speed at which the bullet is traveling along it's trajectory.
Air resistance and gravity.
50 seconds
no! all bullets fall. A bullet dropped from the edge of a table at the same time a bullet at the same table height leaves a barrel hits the ground at the same time.
No- or minimal at best. Acceleration of the bullet comes from gas expanding inside the barrel, pushing the bullet. Once it leaves the barrel, (or within a VERY short distance) gas is no longer pushing, and acceleration stops, and bullet begins to slow from air resistance.
A bullet leaves a gun barrel because it is forced out by the pressure of burning gasses.
It is the opening at the front of the gun where the bullet leaves the barrel.
Smooth-bore is like a tube, think of it as a straight pipe. Rifling is a pipe with grooves swirling around on the inside of the pipe. This makes the bullet spin as it travels down and leaves the barrel. This spinning makes the bullet fly straighter than a bullet fired from a smooth-boar barrel.
It is the hole at the front end of the barrel where the bullet leaves the gun.
how fast it is going
No, a sabot slug does not rise after it leaves the barrel of a gun. No bullet rises after it leaves the barrel of a gun. It always falls from the line of sight of thebarrel. All firearms have to be "sighted in" a bit high to hit a target downrange. At close range, there is little time for a bullet to drop and hit "low" on the target. Down range, however, the drop is more significant. The more time a bullet is in flight, the more it drops below the line of sight of the barrel. But a bullet always begins to drop below the line of sight of the barrel after it leaves the muzzle. Always.
What causes it to rotate is the rifling in the barrel. What causes it to continue to rotate after it leaves the barrel is centrifugal force.
Rifling in the barrel is actually grooves cut into the barrel by the manufacturer to cause the bullet to spin as it leaves the barrel. Before rifling the bullets would tend to tumble when they left the barrel causing them to have shorter range and be less accurate.
