A person is standing on a level floor. His head, upper torso, arms, and hands together weigh 470 N and have a center of gravity that is 1.13 m above the floor. His upper legs weigh 108 N and have a center of gravity that is 0.755 m above the floor. Finally, his lower legs and feet together weigh 87.1 N and have a center of gravity that is 0.250 m above the floor. Relative to the floor, find the location of the center of gravity for the entire body.

total weight = 470+108+87.1

total moment = 470(1.13)+108(.755)+87.1(.25)

cg height = total moment / total weight

IMAGINE- a building 6400km. high. On the ground floor, a person weighs 175lbs when he steps on a spring scale how much would the man weigh on the same scale if he were standing at the top floor?
