By dividing the moments around the y-axis and around the x-axis,
respectively, by the total mass, the x- and y-coordinates of the centre of
mass may be determined.
formula's:
- [tex]y.cm=\left[\begin{array}{ccc}\frac{m1y1+m2y2+...}{m1+m2+...}\end{array}\right][/tex]
- [tex]x.cm=\left[\begin{array}{ccc}\frac{m1x1+m2x2+....}{m1+m2+.....}\end{array}\right][/tex]
- centre of two mass particle system: [tex]\left[\begin{array}{ccc}(m1+m2) r.cm =(m1 )r1+(m2) r2\end{array}\right][/tex]
