Two trains, one traveling at 72km/h and the other at 144km/h are headed toward each other on straight level track. When they are950m appart, each engineer sees the other train and applies the brakes. If the brakes decelerate each train at a rate of 1.0m/ssquared, determine if the there is collision.
