recoil velocity equation physics


Anybody can answer Detailed answers to any questions you might have The victim isn’t moving before the hit, so he starts without any momentum. (b) Calculate the increase in internal kinetic energy (that is, for the ship and the shell). Caculate energy and momentum of emitted photon. To find the velocity of the Earth, use the momentum equation, p = m*v. This equation rearranges to v=p/m. I used an expansion of the square root and approximated. After you input the necessary data such as the bullet weight, bullet velocity, powder charge weight, and the firearm weight it will output the recoil impulse, recoil velocity, and the recoil … Anybody can ask a question This energy is the figure most often given in books and magazines.

Recoil velocity is the speed with which the rifle or pistol recoils when the bullet is fired. Start here for a quick overview of the site 3)What is the momentum of photon p p (subscript p for photon) with energy E (remember photon travels with speed of light c)? Learn more about hiring developers or posting ads with us 4)Apply conservation of momentum, i.e. Physics Stack Exchange works best with JavaScript enabled What I found surprising in the pictures was … Deflecting the gases 90 degrees does take the powders mass and velocity out of the recoil equation so it does reduce the recoil. By substituting into this equation, v = (10 kg*m/s)/(6*10 24 kg) v = 1.67*10-24 m/s (downward) Another way to write the velocity of the earth is to write it as. As always, these things are related to some extent. p i = m 1 v i 1. Calculate recoil from muzzle velocity and bullet, powder and rifle weight. By using our site, you acknowledge that you have read and understand our Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Recoil Energy Calculator. It is just kinetic energy (KE). Physics help? That is, the first term is the total energy, and so the second should be unnecessary. It's a little bit weird to think about whether the momentum is being transferred to the electron or the nucleus, but it seems like it must be transferred to both somehow?One way to check the work (which I don't wanna do) is to try to get the same expression by only balancing energies and using $\frac{1}{2}mv^2$.Thanks for contributing an answer to Physics Stack Exchange! JavaScript is disabled. Recoil. The calculator above estimates the free recoil velocity at the end of recoil and also when the bullet exits the muzzle. Therefore, the initial momentum, p i, is simply the initial momentum of the enforcer, Player 1.To put this equation into more helpful terms, substitute Player 1’s mass and initial velocity (m 1 v i 1) for the initial momentum (p i):. 1)First find recoil energy (E R). 0.00000000000000000000000167 m/s Use mass m and velocity v. 2)Now relate the equation in (1) to atom's momentum p a. a for atom. Explanation of terms. I assumed the Doppler effect for light was involved, and I got exactly double the result the book did (Bransden and Joachain, Chapter 1, problem 21.) Discuss the workings and policies of this site Stack Exchange network consists of 177 Q&A communities including Thus, we have,$$E_\gamma=\frac{m_ee^4}{8h^2\epsilon_0^2}\left (\frac{1}{n_1^2}-\frac{1}{n_2^2}\right ),$$where we have used the solution to the energy states of a hydrogen atom coming from using a Coulomb potential to describe the potential energy of the system.Then, we impose the conservation of momentum condition that $P_\gamma=P_{atom,f}-P_{atom,i}$. But the answer given above does not work. Recoil Velocity?A 9.00 107 kg battleship originally at rest fires a 1200 kg artillery shell horizontally with a velocity of +625 m/s. Unless, you had meant to type m0? I can't find the factor of two anywhere.

Use this calculator to calculate the recoil on you rifles, handgun, and other firearms.

(a) If the shell is fired straight aft, there will be negligible friction opposing the ships recoil velocity.
