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 kgkg and is traveling east with a velocity of magnitude 4.80 m/sm/s. Find the final velocity of the car in each case, assuming that the handcar does not leave the tracks.
