    Answer:

    See the explanation below, and the different answers

    Explanation:

    It is important to clarify that the mass is always preserved, that is, it does not vary regardless of the location of the person, whether the moon, Saturn, Mars. The value that changes is the weight, due to the gravity of each planet.

    On Earth

    m = 86[kg]

    w = m * g

    where:

    g = gravity acceleration = 9.81[m/s^2]

    w = weight = [N]

    w = 86 * 9.81

    w = 843.66 [N]

    On the Moon

    m = 86[kg]

    w = m * g

    where:

    g = gravity acceleration * (1/6) = 9.81 * (1/6) = 1.635 [m/s^2]

    w = weight = [N]

    w = 86 * 1.635

    w = 140.61 [N]
