In a game of freeze, a person freezes into a position shown below. As a percentage of total body mass, the head is 10%, the two arms are 10%, the trunk is 46%, and the two legs are 34%.  The center of mass for each segment is given as an (x,y) coordinate, both units in cm: head = (130, 150), arms = (110, 75), trunk = (65, 95), and legs = (0, 35).   Assume the body mass for the individual is 75 kg and their total height is 160 cm.  The length of the feet is roughly 10 cm.    Determine the x and y-coordinates of the person's center of mass for this pose. Show all steps. Show the location of the center of mass on the diagram. Is this pose stable or unstable? Explain.

Question

In a game of freeze, a person freezes into a position shown below. As a percentage of total body mass, the head is 10%, the two arms are 10%, the trunk is 46%, and the two legs are 34%.  The center of mass for each segment is given as an (x,y) coordinate, both units in cm:

head = (130, 150),
arms = (110, 75),
trunk = (65, 95), and
legs = (0, 35).  

Assume the body mass for the individual is 75 kg and their total height is 160 cm.  The length of the feet is roughly 10 cm. 

 

  1. Determine the x and y-coordinates of the person's center of mass for this pose. Show all steps.
  2. Show the location of the center of mass on the diagram.
  3. Is this pose stable or unstable? Explain.
