Sample questions

1. 1.Which statement about the centre of mass (CM) of a system is NOT correct?
   • A.The total linear momentum equals total mass times CM velocity (P = MV)
   • B.The CM moves as if all mass were there and all external forces acted at that point
   • C.Determining the CM motion requires knowledge of the internal forces
   • D.If the total external force is zero, the CM velocity stays constant
