A system consists of the following masses loacted in the xy- plane: 3.0 kg at the point (0,5), 7.5 kg at the point (3,8) and 7.0 at the point (-3, -6). Find the distance from the origin to the center of mass.

x cm: (3*0+7.5*3+7*-3)/17.5 7 cm:(3*5+7.5*8+7*(-6))/17.5 distance to cm; sqrt( (xcm)^2+(ycm)^2 )
