Jogging Jake runs along a train flatcar that moves at the velocities shown. In each case, Jake’s velocity is given relative to the car. Call direction to the right positive. Rank the following from greatest to least: (a) the magnitude of Jake’s momentum relative to the flatcar and (b) Jake’s momentum relative to an observer at rest on the ground.
