Problem $14\mathrm{.}014-$ A system consists of three particles

A system consists of three particles $A,B,$ and $C.$ We know that $m_A=3kg,m_B=2kg,$ and $m_C=4kg$ and that the velocities of the particles expressed in $\frac{m}{s}$ are, respectively,

$v_A=4i+2j+2k,v_B=4i+3j,$ and $v_C=-2i+4j+2k$

Problem $14\mathrm{.}014.$a $-$ The position vector

Determine the position vector $\frac{?}{\text{b}\text{a}\text{r}}(r)$ of the mass center $G$ of the system. $($Round the final answers to three decimal places

The position vector $\frac{?}{\text{b}\text{a}\text{r}}(r)=1m$
