Separation of mmotion of a systme of particles into motion of the centre of mass and motion about the centre of mass
Show `vec L = L = vec L + vecM R xx vecV` where `vec L = Sigma vecr_i xx vecp_i` is the angular momentum of the system about the centre of mass with velocities taken relative to the centre of mass. Remember `vecr_i = vecr_i - vecR`, rest f the notation is the standard notation used in the chapter. Note `vecL and vecMR xx vecV` can be said to be angular moemnta respectively about and of the centre of mass of the system of particles.
