## Analysis of Gymnast's Center of Gravity

Many aspects of a gymnast's motion can be modeled by representing the gymnast by four segments consisting of arms, torso (including the head), thighs, and lower legs, as depicted in the figure below.

![Gymnast](image-link) 

### Diagrams

- **Figure (a):** Shows a visual representation of the gymnast lying down on a flat surface, with the legs elevated at a 60° angle above the horizontal.
- **Figure (b):** Illustrates a simplified physical model of the gymnast using arrows to indicate lengths \(r_{cg}\) that locate the center of gravity of each body segment (arms, torso, thighs, and legs). The coordinate system is provided with the y-axis vertical and the x-axis horizontal.

### Data Table

The table below provides the masses, lengths, and center of gravity locations for each of the gymnast’s segments. Please note that the masses for the arms, thighs, and legs include both appendages.

| Segment | Mass (kg) | Length (m) | \(r_{cg}\) (m) |
| ------- | --------- | ---------- | -------------- |
| Arms    | 6.81      | 0.548      | 0.242          |
| Torso   | 33.6      | 0.613      | 0.337          |
| Thighs  | 14.1      | 0.370      | 0.149          |
| Legs    | 7.58      | 0.350      | 0.227          |

### Objective

Use the data provided and the coordinate system shown in Figure (b) to locate the center of gravity of the gymnast shown in Figure (a). Provide your answers in meters (m), rounded to at least three significant figures.

#### Center of Gravity Calculation

To calculate the \(x_{cg}\) and \(y_{cg}\):

\[ x_{cg} = \boxed{\_\_\_\_} \text{ m} \]

\[ y_{cg} = \boxed{\_\_\_\_} \text{ m} \]
