railway flatcar of mass

    1. Men and flatcar

N men, each with mass m , stand on a railway flatcar of mass M . They jump o ff one end of the flatcar with velocity u relative to the car. The car rolls in the opposite direction without friction.

      1. What is the final velocity of the flatcar if all the men jump o ff at the same time?

      2. What is the final velocity of the flatcar if they jump o ff one at a time? (The answer can be left in the form of a sum of terms.)

      3. Does case ( a ) or case ( b ) yield the larger final velocity of the flatcar? Can you give a simple physical explanation for your answer?
