In order to avoid the extra energy and time required in starting and stopping, whenever possible trains are loaded through a vertical chute which drops heavy loads directly into the moving train car beneath. The modern average locomotive and a single empty train car have a mass of approximately 23000 kg. If the train passes beneath shoot with a velocity of 6 meters per second when a 5200 kg load of gravel and stone is dropped into the empty train car beneath determine b)What is the final velocity of the train after the load has been delivered?
