Two trains, traveling toward one another on a straight track, are 400m apart when the engineers on both trains become aware of the impending collision and hit their brakes. The eastbound train, initially moving at 99.0km/hr slows down at 3.40 m/s^2. The westbound train, initially moving at 124 km/hr, slows down at 4.20 m/s^2. Will the trains stop before colliding?
