Part A

Mass $M_A=35kg$ and mass $M_B=29kg.$ They have velocities $($in $\frac{m}{s})$ vec$(v{)}_A=12$hat$(i)-22$hat$(j)$ and vec$(v{)}_B=-20$hat$(i)+11$hat$(j).$

Determine the velocity of the center of mass of the system.

Express your answer using two significant figures. Enter your answers numerically separated by a comma.

$v_{C{M}_x},v_{C{M}_y}=$
