Quizplus · Accepted Answer

When Jogging Jake runs in the direction of motion of the flatcar, his momentum adds to that of the flatcar. When he runs in the opposite direction, his momentum subtracts from that of the flatcar. Therefore, the combined momentum of Jake and the flatcar will be less when he runs in the opposite direction.
