Two trains, traveling toward one another on a straight track, are 325 m apart when the engineers on both trains become aware of the impending collision and hit their brakes. The eastbound train, initially moving at 101 km/h, slows down at 3.40 m/s². The westbound train, initially moving at 118 km/h, slows down at 4.80 m/s². Will the trains stop before colliding? If the trains stop before colliding, what is the distance d separating them once they stop? If the trains do not stop before colliding, what initial separation d would have been needed to avert a disaster?
