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
