    Answer:

    41.3 m/s^2

    Explanation:

    The acceleration of an object is the rate of  change of the velocity of the object.

    It is a vector quantity, so it has a magnitude and a direction.

    The acceleration is given by:

    a=\frac{v_f-v_i}{t}

    where

    v_f is the final velocity

    v_i is the initial velocity

    t is the time taken for the velocity to change

    If the acceleration is positive, the direction is the same as the initial velocity; if the acceleration is negative, the direction is opposite to the initial velocity.

    In this problem:

    v_i=0 is the initial velocity

    v_f=124 m/s is the final velocity

    t = 3 s is the  time

    So, the acceleration is

    a=\frac{124-0}{3}=41.3 m/s^2
