a snowball comes apart as a child throws it north, resulting in two halves traveling away from the child. the child is standing 12 feet south and 6 feet east of the school door, along an east-west wall. one fragment flies off to the northeast, moving 2 feet east for every 5 feet north of travel, and the other moves 2 feet west for every 5 feet north of travel. write an absolute value function that describes the northward position, n(e), of both fragments as a function of how far east of the school door they are. how far apart are the fragments when they strike the wall?
