A railroad handcar is moving along straight, frictionless tracks with negligible air resistance. In the following
cases, the car initially has a total mass (car and contents) of 180 kg and is traveling east with a velocity of
magnitude 5.10 m/s. Find the final velocity of the car in each case, assuming that the handcar does not
leave the tracks.
