Easy bio a person is standing on a level floor. his head, upper torso, arms, and hands together weigh 438 n and have a center of gravity that is 1.28 m above the floor. his upper legs weigh 144 n and have a center of gravity that is 0.760 m above the floor. finally, his lower legs and feet together weigh 87 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 his entire body.

1.034 m above the floor

Explanation:

The location of center of body for a compound body, when the weights are given is calculated as:

where,

is the center of gravity of the entire body

W = weight of the individual body

x = center of gravity of the individual body

Thus on substituting the values we get,

or

or

Hence, the center of gravity of the entire body lies 1.034 m above the floor
