    Answer:

    13.2 m/2

    Explanation:

    As airplane accelerates uniformly:

     final velocity^2 = initial velocity^2 + 2 * acceleration * displacement

    final velocity is given as +150.0

    initial velocity is given as +10.0

    displacement is given as 850.0

    Substituting into equation:

    150^2 = 10*2 + 2 * acceleration * 850

    22500 – 100 = 2 * acceleration * 850

    acceleration = 22400/2/850 = 13.18 =13.2 m/s
