A girl in a bumper car (with a combined mass of 230 kg) is traveling at 3.8 m/s due north. A boy in a bumper
car (with a mass of 220 kg) also is traveling due north ahead of the girl but is moving at only 1.5 m/s. The girl
catches the boy's bumper car and they have a collision. Afterward, the boy is traveling at 3.1 m/s north. What
is the magnitude and velocity of the girl's bumper car? (Round your answer to the nearest tenth.)
