As a percentage of total body mass, the head is 10%, the two arms are 10%, the trunk is 56%, and the
two legs are 24%. The center of mass for each segment is given as an (x,y) coordinate, both units in
cm: head = (0, 165), arms = (0, 115), trunk = (0, 95), and legs = (0, 35). Assume the body mass for the
individual is 88 kg and their total height is 180 cm.
a. Determine the x and y coordinates of the center of mass.
Center of mass (x, y) = (
Center of mass (x, y) = (36.10
b. When the body bends over to pick up an object, the body's center of mass changes. Determine the
x and y coordinates of the center of mass given that the body segments have centers of mass at the
following coordinates: head = (95, 75), arms=(70, 50), trunk = (35, 75), and legs = (0, 35).

Please answer the following question(s):
1.
earch
The center of mass for a human body can be determined by a segmental method. Using cadavers, it
is possible to determine the mass of individual body segments (as a proportion of total body.
mass) and the center of mass for each segment (often expressed as a distance from one end of the
segment). Finding the overall body center of mass can be a complex calculation, involving more than
10 body segments. Below, we will look at a simplified model that uses just six segments: head, trunk,
two arms, and two legs.
