Equation for force from Vf, mass, and joules?

[ryan31394]

So I'm doing some research regarding firearms and need to know the amount of force on the bolt assembly as the bullet is fired. Using a .45 caliber Federal bullet, the mass of the projectile is 15 g, the energy is 500j, and the Vf is 260 m/s. I need to know how to convert these numbers into a function of force, and, if possible, into acceleration. Essentially, I'm wanting to know the acceleration of a given mass based on the force or acceleration produced by the bullet. If any more information is needed, please let me know and I'll do my best to produce it. Thanks!

Welcome to the PF.

Wikipedia has a reasonable intro article about the subject of firearm physics:

http://en.wikipedia.org/wiki/Physics_of_firearms

If you don't understand something in the article, post a quote here and we should be able to help you understand it.

You should research the topic 'internal ballistics'.
