Ared train traveling at 72km/h and a green train traveling at 144km/h are headed towards each other along a straight, level track. when they are 950m apart, each engineer sees the other's train and applies the breaks. the breaks slow each train at the rate of 1.0m/s^2. is there a collision? if so, give the speed of the red train and the speed of the green train at impact, respectively. if not, give the separation between the trains when they stop.
