I came across this from a book saying that:
If all the co-ordinates and velocities are simultaneously specified, it is known from experience that the state of the system is completely determined and that its subsequent motion can, in principle, be calculated. Mathematically, this means that, if all the co-ordinates q and velocities dq/dt are given at some instant, the accelerations d[tex]^{2}[/tex]q/dt[tex]^{2}[/tex] at that instant are uniquely defined.
May i know what is meant by the last sentence?
