Find the average force exerted on a bullet by a rifle

  1. Apr 29, 2015 #1
    1. The problem statement, all variables and given/known data
    A rifleman is shooting at a target at a firing range. The rifle has a mass of 4.0kg. When the gun's trigger is pulled, a bullet of mass of 10g will exit the rifle's barrel at a speed of 800m/s. The rifle is stationary at the instant the trigger is pulled.
    Given that the rifle and the bullet were in contact for 35ms, find the average force exerted on the bullet by the rifle.

    2. Relevant equations


    3. The attempt at a solution
    I was thinking dividing the impulse by time, but I don't think the force is high enough. Otherwise I have no idea as to how to solve this.
