    Another Physics problem

    I've worked out all my problems and got stuck on this one. I am uncertain on how to set this problem up.

    A crate has a mass of 27 kg. What applied force is required to produce an acceleration of 3 m/s2 if the frictional force is known to be 76 N?

    F_{net} = ma

    F_A - f = ma

    F_A = ma + f

    F_A = 27 x 3 + 76 = 157N

    Doesn't look right. Not sure
