Two trains, traveling toward one another on a straight track, are 375 m apart when the engineers on both trains become aware of the impending collision and hit their brakes. The eastbound train, initially moving at 105 km/h, slows down at 3.90 m/s. The westbound train, initially moving at 121 km/h, slows down at 4.20 m/s. Will the trains stop before colliding? Yes d = No 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? m
