Ared train travelling at 72 km/h and a green train travelling at 144 km/h are headed toward each
other along a straight, level track. when they are 950 m apart, each engineer sees the other train
and applies the brakes, which slow each train at the rate of 1.0 m/s2. is there a collision? if yes,
give the speed of the red train and the speed of the green train at impact, respectively. if no, give the
separation between the trains when they stop.
