Problem 23PE

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?

Solution 23PE

Step 1 of 5

Two loaded train cars moving towards each other, the first car having the mass moving with velocity and the second train car with mass of moving with velocity . After the collision, the cars are coupled together by being bumped into one another. Here we need to calculate the final velocity of that coupled train .

Given data,

Mass of first train car,

Velocity of first train car,

Mass of second train car,

Velocity of second train car,

To find,

The final velocity of that coupled train
