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 toware each other. Car 1 is traveling east at 6 m/s and has a mass
of 3,154 kg. Car 2 is traveling west at 23 m/s and has a mass of 8,296 kg.
After the collision, car 1 has a final velocity of 7 m/s west. What is the final
velocity of car 2?
A. 23 m/s west
B. 18 m/s west
O C. 23 m/s east
D. 18 m/s east
