A 28.6-g bullet is fired from a rifle. It takes 2.36 × 10-3 s for the bullet to travel the length of the barrel, and it exits the barrel with a speed of 710 m/s. Assuming that the acceleration of the bullet is constant, find the average net force exerted on the bullet.

  • physics - ,

    The bullet goes from rest to a speed of 710 m/s in 2.36 * 10^-3 s

    v = a*t

    where v is the speed, a is the acceleration, and t is time

    710 = a * 2.36*10^-3

    Solve for a

    Force = m*a

    where m is mass
