  1. Sep 21, 2009 #1
    1. The problem statement, all variables and given/known data
    A 13.0 box is released on a 32 incline and accelerates down the incline at 0.10 .

    a) Find the friction force impeding its motion.
    b)What is the coefficient of kinetic friction?

    2. Relevant equations

    3. The attempt at a solution

    Hey man include the units for your numbers. You should draw the free body diagram and resolve the forces acting on the box into the x and y component so you can find the frictional force. Use uN to find the coefficient of kinetic friction.
