Which of the following is not an appropriate unit for momentum? g*m/s kg*m/hr km*m/s g*cm/min

      Momentum is defined as "It is the quantity of motion of moving body, measured as a product of its mass and velocity".

Mathematically, p =m.v ;

                             = (kg . m/s)

                  where ,

                                         mass in kg

                                   velocity in m/s

and 1and 1

the answer is kevlar
