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. 120m/s. (the minus indicates direction of motion. ) what is their final velocity?.

With any turning vehicle, the rear wheels follow a shorter path than the front wheels. the longer the vehicle is, the greater the difference will be. truck drivers initially swing out before making a turn. what isn't shown in this illustration is as car straightens out, the front wheels must travel a greater distance and the tail end drags on the shortest path.

Maybe because he failed the classes or is very accelerated.
