A rifle is shot straight up and the bullet leaves the barrel at a speed of 245 ms How long will it take the bullet to hit the ground?
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.

Does a 22 cal bullet rise at 75 yards?
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.
A rifle is shot straight up and the bullet leaves the barrel at a speed of 245 miles per second How long will it take the bullet to hit the ground?
Assuming no air resistance, the time for the bullet to hit the ground will be approximately 228 seconds, or about 3 minutes and 48 seconds. This is calculated by using the formula t = 2*v/g, where v is the initial velocity of the bullet and g is the acceleration due to gravity.
How does a bullet leave a gun?
A bullet leaves a gun barrel because it is forced out by the pressure of burning gasses.
What is a muzzle for a gun?
It is the opening at the front of the gun where the bullet leaves the barrel.
What is the difference between rifled and smoothbore?
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.
What would cause a bullet to explode after it leaves a rifle barrel?
how fast it is going
What is a muzzle in a gun?
It is the hole at the front end of the barrel where the bullet leaves the gun.
Does a shotgun sabot slug rise after it leaves the barrel of the gun?
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.
Does a bullet shot from a gun undergo any acceleration after it leaves the barrel?
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.
What makes a bullet spin?
The barrel of the gun has lands and grooves (grooves and ridges) cut in a spiral. The bullet molds to these and starts to spin as it moves down the barrel. The bullet just continues to spin after it leaves the barrel.Correct. The ridges are known as 'lands'. It is possible to calculate how fast a bullet will spin if you know the twist rate of the barrel and the velocity of the bullet. My AR15 has a twist rate of 1-in-8 ie for every eight inches the bullet travels down the barrel, the bullet is rotated once. It fires a .223 round at approx 2,800 feet per second so... The formula is (bullet velocity x 720)/twist rate so... (2,800x720)/8 is an incredible 252,000RPM!
What causes a bullet to rotate on exit?
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.
When a bullet leaves a gun the bullet has what type of energy?
The bullet has a great deal of kinetic energy, because of its high speed. It also has a little bit of potential energy relative to the ground, because of its height above the ground.
