Question 15 of 20
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
