    Given v_in = 20 m/s and a = 3 m/s2, assuming that the body moves at constant acceleration, the motion is modeled by the equation:

    s (t) = (v_in) t + (1/2) a (t^2)

    where s (t) is the distance traveled

    substituting the given,

    s (t) = 20t + (3/2) (t^2)

    at t = 3

    s (t) = 20 (3) + (3/2) (3) ^2

    = 73.5 m
