Coefficient of friction help

  1. Nov 16, 2005 #1
    I need help on this question, The coefficient of friction between a 4.0 kg box and the floor is 0.60. How large of a horizontal force is necessary to give the box an acceleration of 2.0m/s²?

    that sounds suspiciously like a homework problem

    Friction force = (coefficient of friction) * (normal force)
    F = ma

    all you need
