Car A is traveling at a constant speed vA = 125 km/h at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.0 m/s² until a speed of 168 km/h is achieved, and that speed is then maintained. Determine the distances required for the police officer to overtake car A. Neglect any nonrectilinear motion of P. A

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.
