A non-uniform rod AB AB\,AB has length 5 m and mass 12 kg. It is suspended horizontally by vertical strings at A A\,A and BBB. The tension in the string at A A\,A is 49 N.
Use g=9.8 m s−2g = 9.8\text{ m s}^{-2}g=9.8 m s−2.
Find the distance of the centre of mass of the rod from AAA, giving your answer to 3 significant figures.
