Engineers are using computer models to study train collisions to design safer
train cars. They start by modeling an elastic collision between two train cars
traveling toward each other. Car 1 is traveling south at 18 m/s and has a full
load, giving it a total mass of 14,650 kg. Car 2 is traveling north at 11 m/s and
has a mass of 3,825 kg. After the collision, car 1 has a final velocity of 6 m/s
south. What is the final velocity of car 2?
A. 35 m/s north
B. 81 m/s south
C. 81 m/s north
D. 35 m/s south
