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 1.50 x 105 kg and a velocity of (0.35 m/s)î , and the second having a mass of 1.10 x 105 kg and a velocity of –(0.10 m/s)î . What is their final velocity?

3. 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 1.50 x 105 kg and a velocity of (0.35 m/s)î , and the second having a mass
of 1.10 x 105 kg and a velocity of –(0.10 m/s)î . What is their final velocity?
V = (0.30 m/s)î
V21 = -(0.12 m/s)î
