A red train traveling at 72 km/h and a green train traveling at 144 km/h are headed
Chapter 2, Problem 78(choose chapter or problem)
A red train traveling at 72 km/h and a green train traveling 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’s train and applies the brakes. The brakes slow each train at the rate of \(1.0 \mathrm{m} / \mathrm{s}^{2}\). Is there a collision? If so, answer yes and give the speed of the red train and the speed of the green train at impact, respectively. If not, answer no and give the separation between the trains when they stop.
