Momemtum problem

  1. Oct 29, 2013 #1
    1. The problem statement, all variables and given/known data
    A bullet of mass m is fired into a block of mass M that is at rest. The block, with the bullet embedded, slides distance d across a horizontal surface. The coefficient of kinetic friction is μk.

    Find an expression for the bullet's speed vbullet.
    Express your answer in terms of the variables m, M, μk, d, and appropriate constants.


    2. Relevant equations
    p=mv




    3. The attempt at a solution

    v(bullet)=Msqrt(2μkgd)/m
