    Answer:

    the final velocity of the car is 59.33 m/s [N]

    Explanation:

    Given;

    acceleration of the car, a = 13 m/s²

    initial velocity of the car, u = 120 km/h = 33.33 m/s

    duration of the car motion, t = 2 s

    The final velocity of the car in the same direction is calculated as follows;

    v = u + at

    where;

    v is the final velocity of the car

    v = 33.33 + 13 x 2

    v = 59.33 m/s [N]

    Therefore, the final velocity of the car is 59.33 m/s [N]
