    Answer:

    The average net force on the truck is 375 Newtons.

    Explanation:

    Using Newton’s 3rd equation of motion, we have :

    v^{2} - u^{2} = 2×a×s

    where, v = final velocity = 25 m/s

    u = initial velocity = 20 m/s

    a = acceleration

    s = distance traveled = 300 m

    Using these values in the above equation, we get acceleration = 0.375 m/s^{2}

    Using Newton’s second law, we have:

    F=m×a

    where m = mass = 1000 kg

    a= acceleration = 0.375 m/s^{2}

    Putting values we have F=375 N
