Two trains, one traveling at 60 mi/hr and the other at 80 mi/hr, are headed toward one another along a straight level track. When they are 2.0 miles apart, both engineers simultaneously see the other’s train and apply their brakes. If the brakes decelerate each train at the rate of 3.0 ft/s2, determine whether there is a collision. Show complete step-by-step process and solution.

Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.
