If three point masses m, m2, and m3 have position vectors r,, r2, and r3 respectively, relative to some origin, then the position vector of their centre of mass relative to the origin is given by m¡r, + m2r2 + m3r3 rCOM = (m, + m2 + m3) If the vectors a and b above represent the position vectors of a 3 kg point mass and a 2 kg point mass respectively (where the units of distance are considered to be subsumed within i, j, and k), calculate where a third point mass of 2 kg would need to be positioned to make the centre of mass of the system lie at the position
