Train 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 150,000 kg and a velocity of 0.300m/s, and the second having a mass of 110,000 kg and a velocity of -0.120m/s. (the minus indicates direction of motion.) what is their final velocity?
