(equal and opposite reaction)

if a gun recoil kinetic energy (ke) is same as bullet kinetic energy then :

say 0.02 kilogram slug @ 1 000 m/s the ke 0.5*m*v^2 = 10 000 joules (j)

say gun @ 1 kg then : 10 000 j = 1 * v^2 , then v = sq root 10 000 = 100 m/s

actually, last line should read:

say gun @ 1kg then : 10 000 j = (1 * v^2)/2, then v=sq root 20 000=141m/s

The recoil velocity can be calculated using the principle of conservation of momentum. It is given by the formula: recoil velocity = (mass of projectile / total mass) * velocity of projectile. This formula accounts for the momentum of both the projectile and the system it is being fired from.

A rifle of mass 2 kg is suspended by strings the rifle fires a bullet of mass 0.01 kg at a speed of 200 ms the recoil velocity of the rifle is what?

Since momentum is conserved in this system, the initial momentum of the rifle and bullet is equal to the final momentum of the rifle. You can find the recoil velocity of the rifle by setting up the equation: (2 kg) * V = (0.01 kg * 200 m/s). Solve for V to find the recoil velocity of the rifle.


How do you calculate impact Energy for Pneumatic Hammers or how to calculate the Hammer piston velocity?

To calculate impact energy for pneumatic hammers, you can use the formula: Impact Energy = 0.5 * (Piston Mass) * (Piston Velocity)^2. To calculate the hammer piston velocity, you can use the formula: Piston Velocity = √((2 * Impact Energy) / (Piston Mass)).


To find the acceleration of an object moving in a straight line you must calculate the charge in distance during unit of time?

To find the acceleration of an object moving in a straight line, you must calculate the change in velocity during a unit of time. Acceleration is the rate of change of velocity over time, not distance. It is given by the formula acceleration = (final velocity - initial velocity) / time.


How do you calculate force when mass and velocity are given?

Force equals the mass times the rate of change of the velocity.


If you know an objects mass and the force acting upon it you can calculate its acellaration but can you also calculate its maximum velocity If so whats the formula for this?

Yes, you can calculate the maximum velocity of an object if you know its mass, the force acting on it, and the distance it moves. The formula to calculate the maximum velocity is v = sqrt(2 * F * d / m), where v is the velocity, F is the force, d is the distance, and m is the mass of the object.

How can calculate recoil velocity of gun?

The recoil velocity of a gun can be calculated using the principle of conservation of momentum. The formula to calculate the recoil velocity is: Recoil velocity = (mass of bullet * velocity of bullet) / mass of gun. This formula takes into account the mass of the bullet, the velocity of the bullet, and the mass of the gun.


What is the Difference between muzzle velocity and recoil velocity?

Muzzle velocity is the velocity of a bullet as it leaves the firearm's barrel, while recoil velocity is the backward momentum that the firearm experiences when the bullet is fired. Muzzle velocity determines the bullet's speed and trajectory, while recoil velocity affects the shooter's ability to control the firearm during and after firing.


Does recoil velocity answer involve in the calculation of final kinetic energy?

Whether you need it depends on the specific situation, but the recoil velocity does affect the total energy.


What is recoil velocity?

Recoil velocity refers to the momentum imparted to an object, typically a firearm, when it expels a projectile. It is the backwards movement of the object in response to the forward momentum of the expelled projectile. Recoil velocity is important in determining the impact on the shooter and the stability of the weapon.


Velocity in recoil of the recoiling parts of guns?

Depdends on weight of gun, caliber, load and velocity of projectile


What is the Velocity of recoil in recoiling parts of guns?

Depends entirely on the caliber, weight and velocity of the projectile along with the weight of the firearm


What is the recoil of a 5.54 gun?

No way to answer without knowing the weight of the weapon, weight of the projectile, velocity of the projectile


How do calculate the velocity of the boat relative to the shore?

Add the rivers velocity to the boats velocity


What is the formula t calculate acceleration?

The formula to calculate acceleration is: acceleration = (final velocity - initial velocity) / time.


What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 m s?

The only factor needed to calculate change in velocity due to acceleration of gravity is time. The formula to calculate the change in velocity is: change in velocity = acceleration due to gravity * time.


What variables do you use to calculate acceleration?

To calculate acceleration, you need to know the change in velocity (final velocity - initial velocity) and the time taken for that change to occur. Acceleration = (Change in velocity) / (Time taken).


Why do you had to calculate acceleration with velocity?

Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.
