Ok, I'm not the best physics student and I may have bitten off a bit more than I can chew with this project I am trying to find the velocity of a bullet while it is inside the barrel of a gun at three different points. The mass of the bullet is 13g, and the Force acting on the bullet is about 206842710 N/m^2 (I think?) The barrel is 0.114m long, and I'm looking at three intervals (0.038m, 0.076m, 0.0114m) What I'm trying to find is the velocity as well as the kinetic and potential energy acting on the bullet. I am more or less stumped, can anybody help? This project is due tomorrow, I can't see myself sleeping much tonight.
