Direction of the velecity of the cars after collision

Reference no: EM1385270

A railroad car that weighs 20,000lb is traveling eastward with a velocity whose magnitude is 5 fps. A second car, on the same track, that weighs 40,000lb is also traveling in an easterly direction with a velocity of 7.81fps. When the cars collided, they became coupled together and then both cars moved with the same velocity. If friction between the cars and the rails is neglected, what were the magnitude and the direction of the velecity of the cars after the collision?
