Answer
$x_{cm}=+0.105m$ and $y_{cm}=+0.2m$
Work Step by Step
1) On the $+x$ axis:
- The torso, neck and head (mass $m_1=41kg$) are located at $x_1=0$
- The upper legs (mass $m_2=17kg$) are located at $x_2=+0.17m$
- The lower legs and feet (mass $m_3=9.9kg$) are located at $x_3=0.17+0.26=+0.43m$
$$x_{cm}=\frac{m_1x_1+m_2x_2+m_3x_3}{m_1+m_2+m_3}=+0.105m$$
2) On the $+y$ axis:
- The torso, neck and head are located at $y_1=+0.39m$
- The upper legs are located at $y_2=0$
- The lower legs and feet are located at $y_3=-0.26m$
$$y_{cm}=\frac{m_1y_1+m_2y_2+m_3y_3}{m_1+m_2+m_3}=+0.2m$$
