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 98 kg and their total height is 180 cm. Assume all quantities are correct to 3 significant figures. a. Determine the x and y coordinates of the center of mass. Enter to 3 significant figures Center of mass (x, y) = ( cm, cm) 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).
