Physics help asap?!?

If a person weighs 71.8 kg where acceleration due to gravity is 9.79 m/s^2, what would be the difference in weight (in kilograms and in newtons) where the acceleration due to gravity is 9.82 m/s^2??

First right answer gets 5 stars!

    If a person has mass m kg, they have a weight of mg Newtons

    so, with g = 9.79, we have 71.8 x 9.79 = 702.922 N

    and with g = 9.82, we have 71.8 x 9.82 = 705.076 N

    Difference is 705.076 - 702.922 = 2.154 N

    so, 2.15 N in context of the question.

    on a scale in kg

    difference in kg = (71.8*9.82/9.79)-71.8 = 0.22 kg 

    on a scale in N

    difference in N = 0.22*9.805 = 2.16 N

    Difference in weight is

    71.8kg * (9.82 - 9.79)m/s² = 2.15 N

    There is no change in the mass -- still 71.8 kg.

    Rule

    F = mg
