    We must all look for the fg, fn, Ff, and Fnet to get the acceleration.

    1 Fg = 28.6 (-9.81)

    = 0280.56 n

    2 Fn = 280.56 N

    3 Ff = μFn

    = 0.750 * 280.56

    Ff = 210.425 N

    4. Fnet = Fa + Ff

    = 302 - 210.42

    Fnet = 91.576 N

    5. F = ma

    91.576 = 28.6a

    a = 3.2 m/s
