    Answer:

    The final velocity of the object after 2 seconds is 30 m/s

    Explanation:

    Given;

    constant downward acceleration, a =  10 m/s²

    initial velocity of the object falling down, v = 10 m/s

    time of fall, t = 2 s

    The final velocity of the object is given by;

    v = u + at

    where;

    v is the final velocity

    v = 10 + (10)(2)

    v = 10 + 20

    v = 30 m/s

    Therefore, the final velocity of the object after 2 seconds is 30 m/s
