rain cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, the first having a mass of 180,000 kg and a velocity of 0.300 m/s, and the second having a mass of 95,000 kg and a velocity of -0.120 m/s. (The minus indicates direction of motion.) What is their final velocity? ______m/s
