Suppose two loaded train cars are moving toward one another, the first having a mass of 240000 kg and a velocity of 0.325 m/s in the horizontal direction, and the second having a mass of 57500 kg and a velocity of -0.125 m/s in the horizontal direction. What is their final velocity, in meters per second?
