    The acceleration of Mildred is, 1.33 m/s²

    Explanation:

    Given data,

    The initial velocity of Mildred, u = 12 m/s

    The final velocity of Mildred, v = 8 m/s

    The time period of travel, t = 3 s

    The acceleration of Mildred,

    a = (v-u) / t

    a = (8 - 12) / 3

    = - 4/3

    = - 1.33 m/s²

    The negative sign indicates that the Mildred is decelerating.

    Hence, the acceleration of Mildred is, 1.33 m/s²
