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 140,000 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 (in m/s)?
