    Answer:

    The correct answer is “140.8 N“.

    Explanation:

    Given:

    Mass,

    m = 88 kg

    Acceleration,

    a = 1.60 m/s²

    Now,

    The net external force for him will be:

    F_{ext}=Mass\times Acceleration

    By putting the values, we get

               =88\times 1.60

               =140.8 \ N
