Professional Application 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 0.300 m/s, and the second having a mass of 110,000 kg and a velocity of ?0.120 m/s . (The minus indicates direction of motion.) What is their final velocity?

Step-by-step solution In this problem two trains moving in opposite direction with different masses and having different velocities so,find their final velocity when they bumped into one another using the given data respectively: Step 1 of 3 The relation between masses of each car and velocity after sticking together is, …… (1) Here is the mass of first car, is the mass of second car, is the velocity of first car, is the velocity ofsecond car and v is the final velocity. Step 2 of 3 Substitute for , for , for and for .
