Does a fired bullet hit the ground at the same time as a dropped one? There you have it. The y-component of air resistance for the fired bullet still depends on the fired speed of the bullet (since it is proportional to v 2 ). A fired bullet (with air resistance) does not hit the ground at the same time as a dropped bullet .
When a bullet is fired horizontally it takes the same amount of time to reach the ground as a bullet dropped from rest from the same height?
Since gravitational acceleration acts on both a horizontally launched bullet and a vertically dropped bullet in free fall, they both will reach the ground at the same time as their vertical initial velocity is zero .
Does a bullet fall at the same rate?
Because gravity is constant (i.e. it doesn’t change), the bullet will speed up while coming down at the SAME RATE as it slowed down when it was going up . So when it reaches the bottom, it will be going at the same speed as it was when it was first shot from the gun.
Why a bullet from a gun eventually falls to the ground?
How long until a bullet hits the ground?
When you fire a bullet into the air, it typically takes between 20 and 90 seconds for it to come down, depending on the angle it was fired at, its muzzle velocity and its caliber.
When a ball is thrown horizontally and another is dropped which will be faster?
If the ball is thrown exactly horizontally, then it will hit the ground at the same time as the dropped one – but it will a lot further away from the thrower. Where you are going wrong is in assuming there is a horizontal force.
When a ball is thrown vertically and another is dropped which will hit the ground first?
The horizontal and vertical motions of a projectile are independent of each other. So two objects falling under the influence of gravity from the same height will reach the ground simultaneously , regardless of their horizontal velocities.
Where do bullets go if you shoot straight up?
A bullet shot straight up into the sky will fly upwards until its initial kinetic energy is exhausted. It will then start falling and accelerate towards the ground under the influence of gravity until it reaches its terminal velocity, which is limited by air resistance.
How fast do bullets go mph?
When bullets fly through the air, they do so at amazing speeds. The fastest bullets travel more than 2,600 feet per second. That’s equivalent to over 1,800 miles per hour .
Can you dodge a bullet?
Bullet dodging, Scientific American reports, is one such make-believe ability invented by Hollywood. Regardless of your speed and finesse, no human can dodge a bullet at close range . The bullet is simply traveling too fast. Even the slowest handguns shoot a bullet at 760 miles per hour, SciAm explains.
Is it safe to shoot into the ground?
You should never fire your weapon into the ground . The bullet will more than likely ricochet and travel at high speed back up, possibly striking a person or object. It’s best to keep your gun stored properly and only fire in safe conditions unless legally protecting your family and property.
How far does a bullet go until it stops?
A bullet fired straight up on Earth, assuming there’s no wind, might still be able to reach a maximum height of around three kilometers (about 10,000 feet) , and will then fall back down to Earth.
Can a falling bullet penetrate a car roof?
I most often find bullets partially lodged in a composition shingle roof system, but I occasionally find them fully penetrating the roof . I have also seen evidence of this type of damage in TPO/Vinyl roof systems, metal roofs, and modified bitumen roof systems.
How fast does a bullet fall if shot straight up?
If there were no air resistance, the bullet would return to earth going exactly the same speed as it left the gun barrel, i.e. around 2,500 feet per second .
Do bullets break the sound barrier?
In fact, bullets can move fast enough to break the sound barrier . Contrary to what the name might suggest, the sound barrier is not an actual wall or barrier. Rather, it is the hypothetical limit to the speed an object can travel before it exceeds the speed of sound.
Can a bullet leave the atmosphere?
Even a bullet, fired straight up at the maximum speed a gunpowder blast can accelerate it to, will never leave the lowest layer of Earth’s atmosphere . A combination of gravity and air resistance will slow it down until it reaches a maximum height, whereupon it will fall back down to Earth’s surface.
Did one ball hit the ground before the other or did both balls hit the ground at the same time?
Gravity is the force that causes things to fall to earth. When you drop a ball (or anything) it falls down. Gravity causes everything to fall at the same speed. This is why balls that weigh different amounts hit the ground at the same time .
Why do two balls hit the ground at the same time?
Which ball would hit the ground first?
Which ball will hit the ground first if dropped at same time at the same height?
In other words, if two objects are the same size but one is heavier, the heavier one has greater density than the lighter object. Therefore, when both objects are dropped from the same height and at the same time, the heavier object should hit the ground before the lighter one.
Do two objects fall at the same time?
This force is caused by air resistance. The less massive the object is, the more the force of air resistance slows the object down as it falls. If two objects were dropped on the moon, where there is no air, they would fall at the same rate no matter how much they differ in mass.
Which will hit the ground first a heavy or light object?
The force due to gravitation and air resistance. In the absence of air resistance, both heavy and the lighter object will hit the ground at the same time. If the air resistance is present, the air resistance will slow down the lighter object. Therefore the heavier object will hit the ground first .
Will bullets go off in a fire?
How gravity affects a bullet?
The bullet, because of gravity, immediately starts to fall from its original path . Because objects fall faster the longer they fall (up to a certain point), the bullet falls faster and more off of its original path the longer it travels.
What is the slowest bullet?

What gun has the fastest bullet?
The . 220 Swift remains the fastest commercial cartridge in the world, with a published velocity of 1,422 m/s (4,665 ft/s) using a 1.9 grams (29 gr) bullet and 2.7 grams (42 gr) of 3031 powder.
Can a pocket Bible stop a bullet?
Rickey Wagoner, 49, was shot three times at point-blank range and stabbed in the arm, but survived because both bullets aimed at his chest were stopped by a New Testament devotional Bible in his front pocket , according to WHIO. The third bullet struck him in the leg.
Can you dodge a bullet underwater?
Is a jet faster than a bullet?
The horizontal and vertical motions of a projectile are independent, meaning they do not affect each other . The 2-D motion of a projectile can be separated into two 1-D motions: horizontal and vertical. The horizontal motion of a projectile is always constant, if we neglect air resistance.
When a bullet is fired horizontally What is its initial vertical velocity?
What is the horizontal acceleration of a projectile?
Nothing accelerates a projectile horizontally, so horizontal acceleration is always zero .
What is not true about projectile motion?
FALSE – Many projectiles are moving from left to right and from right to left as they simultaneously free fall. Such projectiles have a horizontal motion. While a projectile can have a horizontal motion, it cannot have a horizontal acceleration .
