    Option A. 3 m/s2

    Explanation:

    Given dа ta: Initial velocity = 0 m/s

    Final velocity = 60 m/s

    Time taken = 20 seconds

    Required : acceleration = ?

    Solution: We know that

    Acceleration = final velocity - initial velocity / time taken

    Acceleration = 60 m/s - 0m/s : 20 s

    Acceleration = 60 m/s : 20 s

    Acceleration = 3 m/s2

    So the acceleration produce in the body is 3 meter / second square.
