Hi everyone. I'm quite troubled with this physics question. A .035 kg bullet is fired from a .23 m barrel. The bullet experiences a force of 4500 N while in the gun barrel. What is the kinetic energy of the bullet as it leaves the gun barrel? I don't understand how to figure out the velocity to calculate the KE. Is it possible to calculate the KE from GPE or Work? Our teacher has not taught us this and I don't understand why he is expecting us to answer this question.... (btw. I'm in year 10) Thanks.
