    Answer:

    Explanation:

    All we need here is the equation for frictional force, which is

    f = μF_n where F_n=mg That’s normal force which is the same thing as weight.

    Therefore,

    F_n=(12.3)(9.8) to 2 sig figs so

    F_n=120 and

    f = (.137)(12) to 2 sig figs as well so

    f = 16N
