N women, each with mass m, stand on a railway flatcar of mass M. Tehy jump off one end of the flatcar with velocity u relative to the car. The car rolls in the opposite direction without friction.
A- What is the final velocity of the flatcar if all the women jump at the same time?
B- What is teh final velocity of the flatcar if they jump off one at a time? (The answer can be left in the form of a sum of terms)
