If you shoot the bullet straight horizontal, then it is not going to be in the air as long and the air drag will not have as much time to do negative work on the bullet and slow it down. Note that the air resistance force is always in the opposite direction to the displacement so that the work done by air on the bullet will be negative. When the bullet is shot straight up, it should have time to reach terminal velocity on the way back down.
Also, it is useful to think about the case where there is no air resistance, in this case all the bullets would have the same final speed regardless of angle. I don't know at what speed a bullet is lethal, but you can see that the final speed drops off rapidly with angle. If I had to guess, I would say that a firing angle of 45 degrees could be considered by some as still "shooting in the air".
Also, the lower the angle the larger horizontal distance the bullet would travel. Think about when you see people firing off 'celebration' shots. Sometimes these low angles do happen. One last note. I tried to use my model to determine the range of a fired bullet.
However, I am not sure how range is defined? Is it from a standing position? This leads many to ask the obvious question, "If celebratory gunfire is illegal, then why are guns fired into the air at military funerals and events? Why do we have '21 gun salutes' if this is so dangerous? Unfortunately, most celebratory gunfire that occurs in communities uses live ammunition, which is what results in these potentially lethal consequences. A bullet fired up into the air doesn't cease to be dangerous because it's out of sight; typically between 20 and 90 seconds later but up to two full minutes later , it will eventually come down.
A gun salute, where 7 guns are fired three times apiece, pose no danger to bystanders only In any region where the bullets could come down and land on a human, this would have the potential to injure or even kill others. The most dangerous conditions for celebratory gunfire occur in urban areas with a high population density, when large crowds are outside late at night: the night of July 4th and New Years Eve are typically the peaks of stray bullet injuries from this cause.
Dense, small bullets will achieve higher terminal velocities than lighter, larger bullets, making them more dangerous. At high altitudes, there's less air resistance, meaning that stray bullets will carry more kinetic energy and pose a higher risk of death than at low altitudes.
The behavior that is riskiest to others, though, is firing a bullet at an angle into the air, rather than straight up. Bullets that are fired very close to perfectly vertical will lose the most speed; those that are at an angle can maintain velocities that ensure they will puncture skin, regardless of where or whom they hit. If a bullet is capable of puncturing your skin, it can then go on to do a tremendous amount of Although celebratory gunfire continues to be an unnecessary cause of injury and death in the United States and across the world, there are a number of positive aspects to focus on.
A CDC report in noted that celebratory gunfire in Puerto Rico killed 2 and injured 25 on an annual basis; since , campaigns to reduce that number have successfully eliminated New Years deaths from stray bullets. Raising awareness works. Firing a gun into the air creates a potential hazard for anyone within a two mile radius of the person firing the gun, and the danger will not subside until a full two minutes have passed since the final gunshot.
Although there are no recorded incidents of the person firing the gun also getting hit by their own stray bullet, it remains a frightening possibility, but not the reason it's against the law.
As is often the case, your individual freedom to celebrate ends when it infringes on the lives and safety of innocent bystanders. This is a BETA experience. You may opt-out by clicking here.
There are myths out there that bullets shot into the air go into outer space, or descend with enough of a drag that they are not hazardous. Neither of these beliefs is true. While only a small percentage of bullets shot in the air will actually hit a person or a pet at the velocity to cause serious damage or death, it does happen in addition to property damage to cars, homes, etc.
These injuries happen all across the United States and in many other parts of the world as well. Unfortunately, it is also common here in Houston. As a trauma surgeon, I have witnessed such cases. No one heard a gunshot. No one saw any gun fired in the vicinity, but we found a copper bullet lodged deeply in the top of her skull. Army Maj. Julian Hatcher, who apparently was curious and had some time on his hands, did experiments in Florida in which he fired various weapons — ranging from rifles to machine guns — up into the air, and tried to measure how long it took for the bullets to come down, as well as where they landed.
As he noted in his volume "Hatcher's Notebook," he calculated that a standard. But ballistics researcher James Walker, who holds a doctorate in mathematics and is department director of engineering dynamics at the Southwest Research Institute in San Antonio, says that the altitude attained by a bullet fired straight up would depend upon the type of weapon and projectile, just as it does when fired horizontally.
A handgun, which has a shorter barrel than a rifle and fires ammunition with a smaller cartridge that doesn't contain as much powder, isn't going to send a bullet soaring as high as a rifle will. Different types of rifles and ammunition vary as well. Rifles like the. When fired horizontally, bullets tend to slow down rapidly due to air drag, so that a rifle bullet may be down to half of its initial speed by the time it gets to meters 1, For altitude estimates, Walker pointed to this chart on the website of Close Focus Research , a ballistics testing company, which shows that a.
But no matter how high a bullet goes in the air, however, eventually it will decelerate until its velocity reaches zero, at which point it will begin to fall back to Earth, as detailed in this article on falling bullet injuries in the Journal of Neuroscience Rural Practice.
And most importantly, a bullet is unlikely to fall straight down, as wind can alter its path, Walker says. That makes it difficult to predict where a bullet will land.
Back in Texas, Representative Martinez sought to keep others from being hit by falling bullets, by introducing legislation raising the penalties for discharging a firearm without an intended target, according to The Monitor.
