    Answer:–

    -1 m/s^2

    Explanation:

    The average acceleration is given by dividing the change in velocity by change in time;

    a_f=\frac{v_f-v_i}{t_f-t_i}

    =\frac{(0-11.2)}{(11.2-0)}=-1 m/s^2

    the point to be noted here is if the velocity is to the left we substitute it with a negative sign and if it is to the right we substitute it with a positive sign.
