    Answer:

    86.17m/s

    Explanation:

    Since the motion is of constant acceleration, we can use one of the equations of motion as follows;

    v² = u² + 2as

    Where;

    v = final velocity of the airplane

    u = initial velocity of the airplane

    s = distance covered by the plane

    a = acceleration

    From the question,

    u = 15m/s

    s = 600m

    a = 6m/s²

    Substitute these values into the equation above as follows;

    v² = 15² + 2(6)(600)

    v² = 225 + 7200

    v² = 7425

    v = √7425

    v  = 86.17m/s

    Therefore, the final velocity of the airplane is 86.17m/s
