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), andlegs = (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.
In the expression for calculating the moment of a force about a point o, Mo = rx F, r is the vector that: Runs from the point o to any point on the line of action of the force. Runs from the point o to a line perpendicular to the line of action of the force. Is parallel to the line of action of the force. Runs from any point on the line of action of the force to the point o.
