What was the force exerted on the bullet bringing it to rest?

  1. Jan 24, 2007 #1
    1. The problem statement, all variables and given/known data
    a 3 gram bullet traveling at 350m/s squared hits a tree and slows down uniformly to a stop while penetrating a distance of 12 cm into the tree's trunk. What was the force exerted on the bullet bringing it to rest?

    2. Relevant equations

    3. The attempt at a solutionI know the speed is 350m/s , the weight is .003 kg, and the distance it traveled is .12 m. I cant figure out how to get the newtons so i can get the joules. I am stuck.

    Welcome to the forums. Please note that for homework questions we need to see your working before we can help you. Do you have any thoughts? Hint: how does the work done by the force stopping the bullet relate to the total energy of the bullet before it hits the tree?
