A pair of physics students, Marie and Pierre, are hanging out at the county fair. While riding bumper
cars, they decide to test the law of conservation of momentum. Marle and Pierre rush towards each
other, going 2 m/s and 4 m/s respectively. If Marie bounces backwards at 3 m/s, what is Pierre's final
velocity? Each car (with student included) has a mass of 250 kg.
