    Ridiculous question. Over two weeks, someone had to have addition fluids, food, and eliminated wastes.

    the total kg would be 85 kg. then multiply by 9.8 to find fg. to lose weight he has to have a downward acceleration ( push downwards on a countertop while standing on the scale).

    Lets say that ninja gained those 5kg's of weight over the break. Then he would now weigh 85kg.
    Weight is Mass multiplied by gravity.
    W=Mg
    85 is your mass and 9.8 is gravity on Earth.
    85*9.8=833
    That is the answer to A. c:

    Ninja can loose weight by, as Ali said, pushing downwards on a countertop. He can gain weight by standing on one foot.
