Homework Help: Friction force and coefficent of friction

  1. Jan 18, 2010 #1
    1. The problem statement, all variables and given/known data

    caculate the force of friction and coefficent of fricition acting on a sliding block given that the acceleration at 3.0 m/s sqaure

    2. Relevant equations

    coefficent of friction = fn/ff
    force of friction = u fn = u fg

    3. The attempt at a solution

    im stuck im only given the accelaration and mass is 4 kg too how can i solve this?

    The only force in the horizontal direction is the force of kinetic friction. Use Newton's Second Law to find it.
