What else can I help you with?
If you shot a bullet straight into the air and it fell to land on your head would you die?
Probably. The bullet would be travelling slower than when it left the gun (see related question) but it would still be travelling fast enough to cause injury. In areas of the world where guns are fired into the air in celebration injury from falling bullets is not uncommon.
If i dropped a penny off an airplane and it hits your head can it kill you?
I say NO. If you mean it is dropped and falls vertically. Discover Channel's "Myth Busters" tried to determine if a bullet would kill you if it was fired directly vertical and falls on its own. The bullet or penny would fall at terminal velocity which is about 120mph. However, they will tumble which slows them down more. This velocity and their mass is not enough to kill you.
If a gun is fired straight upward and the bullet leaves the gun at 100ft per second after 2 seconds the velocity of the bullet is 36 feet per second what is the velocity after 3 seconds?
Since the bullet is fired straight upward, it will be decelerating due to gravity acting in the opposite direction of its initial velocity. Thus, at t = 3 seconds, the velocity will be less than 36ft per second but still positive (as it's moving upward). To calculate the exact velocity, you would need to use the kinematic equation for velocity in one dimension.
If you are traveling at the speed of a bullet and then fired a bullet in the opposite direction what happens?
1). Your speed in the forward direction should increase somewhat, since the recoil of the shot adds to your momentum. 2). The bullet you fire in the reverse direction leaves the muzzle with full muzzle velocity and momentum in the reverse direction ... in your frame of reference. Viewed by an observer in the stationary frame of reference ... the one in which you are moving at the speed of a bullet ... the one you fire just dribbles out of the muzzle and falls straight to the ground.
What is a graph of uniform velocity?
A graph of uniform velocity would be a straight line with a constant slope, indicating that the object is moving at a constant speed in a straight line without changing its velocity.

Is it possible to shoot a bullet into space from the ground on earth?
No, it is not possible to shoot a bullet into space from the ground on Earth. Bullets fired from firearms do not have enough velocity to escape Earth's gravity and reach space. Additionally, there are aerodynamic forces, air resistance, and other factors that would prevent a bullet from traveling to space.
If you shoot a gun up what is the velocity of the bullet coming down?
The velocity of a bullet coming down from altitude is the terminal velocity of the bullet fired. Since not all bullets are equal in mass, it would depend on the grain (weight) of the bullet fired, the caliber of the bullet, and the charge behind the bullet (which would determine the highest possible altitude it could reach). To determine the terminal velocity of any bullet, you must first know these variables and plug in those variables to the equation below: That is, * Vt = terminal velocity * m= mass of the bullet * g = gravitational acceleration * Cd = drag coefficient (wind resistance applied to the bullet as it falls) * ? = denisty of the medium through which the bullet is falling (the atmosphere) * A = projected area of the bullet (which can get complicated due to the shape of the ball). Essentially, the following is true: any bullet fired straight upward is not only potentially but very likely as deadly to anyone it might strike when it lands as if that same bullet were fired directly at that person.
If a bullet was fired down through the earth's atmosphere how long would it take and how fast would it be?
That would depend on the mass of the bullet, the bullet's velocity when it left the barrel of the gun, and from how high up the bullet was fired from.

Why does a small bullet can make a clear hole in a glass window but a big stone can only crack it?
I would say this has to do with velocity of the bullet.(speed)

How do you apply the concept of momentum to compare the mass and velocity of a slow moving train and of a high-speed bullet?
The momentum of an object is the product of its mass and velocity. In the case of a slow moving train and a high-speed bullet, the bullet would have a higher momentum due to its higher velocity even if its mass is smaller. This is because momentum is more affected by velocity than by mass.
Whitch bullet flys the farthest?
The bullet that flies the farthest would typically be a smaller, lighter bullet with a higher velocity. Factors such as bullet weight, shape, velocity, and the firearm used can all affect the bullet's flight distance. Generally, bullets fired from rifles with longer barrels and higher muzzle velocities tend to travel farther.
What would better stop a bullet a cow or a car?
The only time that a car will stop a bullet is if you are in Hollywood, or have an armour-plated vehicle. A cow interposing itself between the bullet and yourself would reduce it velocity significantly more.
