Question
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 170 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.
