(20%) Problem 4: 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 270000 kg and a velocity of 0.305 m/s in the horizontal direction, and the second having a mass of 62500 kg and a velocity of -0.115 m/s in the horizontal direction. What is their final velocity, in meters per second? Vf= Grade Summary Deductions Potential
