Collision and friction question

  1. Apr 23, 2015 #1
    1. The problem statement, all variables and given/known data
    This is just a question relating to an assignment im doing, if a steel block mass m1 travelling at velocity v1 and friction of 0.1 hits a concrete barrier travelling at 0 with mass m2 with friction 0.6. they have an inelastic collision and travel 0.1m together.

    2. Relevant equations
    frictional force = mg*coefficient of friction
    3. The attempt at a solution
    for this period of travel, is the friction force acting on the both items = m1*g*0.1+m2*g*0.6
    or is it

    I would guess the former.
