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 125,000 kg and a velocity of −0.120 m/s. (The minus indicates direction of motion.) What is their final velocity (in m/s)?

    Two identical freight cars roll toward one another, on a level track with negligible friction.One car is moving at 2.3 m/s and the other car at 2.9 m/s. After the collision, both cars are coupled and roll together with what speed? How much kinetic energy islost in this collision? ***I get 0.3 as my velocity but Im not sure how to calculate how much kinetic energy is lost in this collision
