Homework Help: Find the force exerted on a bullet as it travels through the barrel

  1. Oct 4, 2011 #1
    1. The problem statement, all variables and given/known data

    A 5.1 g bullet leaves the muzzle of a rifle with
    a speed of 467 m/s.
    What constant force is exerted on the bullet
    while it is traveling down the 0.5 m length of
    the barrel of the rifle?
    Answer in units of N


    2. Relevant equations
    V2=Vo2+2a(x-xo)
    F=ma


    3. The attempt at a solution
    4672=2a(.5-0)
    a=218089

    F=.051*218089
    F= 1112.2539
