A rifle is fired and you are able to measure both the muzzle velocity of the bullet as well as the recoil velocity of rifle how do you explain the fact that the forward velocity of the bullet is great?

The force exerted on the bullet and the recoil force against the rifleman, are equal to each other (for every action there is an equal and opposite reaction). The bullet has a very small mass, and the rifle/rifleman possess a large mass, force is equal to one half mass times velocity squared, F=m/2*v^2. So velocity of the bullet is the square root of twice force divided by mass, small mass equals large velocity. Another way of looking at this problem is to invoke the law of the conservation of momentum: mass(bullet)*muzzle_velocity(bullet) = mass(rifle)*recoil_velocity(rifle). This is an approximation that neglects the momentum carried away the propellant (both spent and unburned) that exits the muzzle after the bullet.

The forward velocity of the bullet is greater than the recoil velocity of the rifle because of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When the bullet is fired forward with high velocity, the rifle experiences a recoil in the opposite direction but with lower velocity due to the mass difference between the bullet and the rifle.

When a rifle fires it accelerates a bullet along the barrel Explain why the rifle must recoil?
When the rifle fires, it propels the bullet forward with force based on Newton's Third Law of Motion: for every action, there is an equal and opposite reaction. The force pushing the bullet forward causes an equal force in the opposite direction, which results in the rifle recoiling backward.
When a bullet is fired from a rifle?
When a bullet is fired from a rifle, a chemical reaction in the gunpowder ignites, rapidly expanding gases build up pressure, and the bullet is propelled out of the barrel at high speed. The rifling in the barrel causes the bullet to spin, improving accuracy and stability. Gravity will eventually cause the bullet to drop due to gravity and air resistance.
Who invented the hypodermic needle media theory?
The hypodermic needle media theory, also known as the magic bullet or bullet theory, was developed in the 1920s and 1930s by researchers such as Harold Lasswell and Paul Lazarsfeld. The theory suggests that media messages are directly and uniformly injected into the minds of passive audiences, shaping their attitudes and behaviors.
What organizational methods work for cause and effect?
Organizational methods that work well for cause and effect include using a flowchart to visually map out the relationships between causes and effects, creating a timeline or sequence of events to show the chain of causation, and using bullet points or lists to clearly outline each cause and its corresponding effect. Additionally, using signal words such as "because," "since," "as a result," or "therefore" can help connect causes and effects in writing.
How can you decorate your assignment?
You can decorate your assignment by using headings, bullet points, numbering, bold or italic text, colored text, relevant images or charts, and a consistent font style to make it visually appealing and easy to read. Be sure to follow any guidelines provided by your instructor.

What is the Difference between muzzle velocity and recoil velocity?
muzzle velocity is the velocity of bullet and recoil velocity is the velocity of gun.
What is the recoil velocity of the pistol when a bullet of mass 20g is fired with a velocity 150ms from a pistol of mass 2kg?
Momentum before = momentum after. Since there was no movement before, momentum before = 0 If you think of the bullet as forward/positive momentum and the gun as backward/negative momentum then the momentum of the bullet plus the momentum of the gun =0 and therefore the momentum of the bullet = the momentum if the gun. momentum = mass x velocity P=m/v 20gx150m/s = 2000g (2kg) x velocity 3000 = 2000v 3000 / 2000 = v v = 1.5m/s
Define trAjectory of the bullet velocity of the bullet velocity?
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.
How does a bullet fired from a gun have ahigh momentum?
Momentum = mass x velocity A bullet has a high momentum because its velocity is really high.
How did Rutherford explain his observation?
he described it as being as tho firing a bullet of a gun forward only for it to turn around and head back the other way
Which should be the best on knocking the bear down- a rubber bullet or a lead bullet with the same momentum explain?
If we consider the bullets of same size,then rubber bullet having less density will have higher velocity and higher kinetic energy than that of lead bullet.Thus rubber bullet can impart more energy.Hence this would be more effective.
How does gravity affect the velocity of a fired bullet?
Gravity adds 32.1 feet per second to the bullet's downward velocity every second after the shot is fired.
Is it possible to shoot a bullet into space from the ground on earth?
Yes, if the bullet is shot with escape velocity.
What goes forward but never back?

Can bullet proof glass withstand a 1000 fps bullet?
It depends on the thickness of the glass and the muzzle energy of the bullet, not just the velocity.
What happens to the velocity of bullet if there are two or more targets?
velocity decrease and at last it becomes zero.
