    Answer:

    The magnitude of the constant acceleration required to do this is 2.07 m/s²

    Explanation:

    Given;

    distance the automobile will travel, d = 0.5 km = 500 m

    initial velocity of the automobile, u = 0

    time of travel, t = 22 s

    Apply the following kinematic equation to determine the constant acceleration;

    d = ut + ¹/₂at²

    500 = 0 + ¹/₂(22)²a

    500 = 242a

    a = 500 / 242

    a = 2.07 m/s²

    Therefore, the magnitude of the constant acceleration required to do this is 2.07 m/s²
