A jump landing model divides the body into three segments: calf, thigh, and upper body. The horizontal ankle marker position is 0.200 m. The knee, hip, and suprasternale horizontal marker positions are given (see Variables in Excel file). The calf center of mass location is 0.420 from the knee to the ankle, the thigh center of mass location is 0.400 from the hip to the knee, and the upper body center of mass location is 0.440 from the suprasternale to the hip. The relative mass of the calf is 0.110, the relative mass of the thigh is 0.260, and the relative mass of the upper body is 0.630. What is the calf segment horizontal center of mass
