The problem involves the conservation of momentum and energy in a scenario where a person fires a gun, leading to recoil. The participants are discussing the kinetic energy transferred to the person after the gun recoils, given specific masses and bullet velocity.
The discussion is ongoing, with participants exploring different interpretations of energy conservation and momentum. Some guidance has been offered regarding the loss of energy during the impact, but no consensus has been reached on the final understanding of the problem.
Participants are working under the assumption that energy is conserved after the impact, but they acknowledge that this may not hold true during the impact itself. There is also a mention of energy loss that needs to be accounted for in the analysis.
You forget to hold your gun against your shoulder and it recoils into you. How much Joules of kinetic energy end up in your shoulder? Assume you and the gun move together in the end.
masses: You=90 kg, gun=10kg, bullet= 0.0085kg
velocity of the bullet = 87m/s

After the impact, energy is conserved (you can't assume conservation during the impact though).
