a person is standing on a level floor. His head , upper torso , arm , and hand together weigh 438N and have a center of gravity that is 1.28 m above the floor. His upper legs weigh 144N and have a center of gravity that is .760 m above the floor. Finally, his legs and feet together weigh 87N and have a center of gravity that is .250 m above the floor. Relative to the floor, find the location of the center of gravity for his entire body

2. Relevant equations

x of cg = W(lever arm) of 1 + W(lever arm) of 2 / W of 1 +W of 2

3. The attempt at a solution

I don't know how to start. But i need to find the lever arm of each one? so 1.28 m = 438N (lever arm) / W?
