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.

Question

As a car comes around a bend onto a straight road moving at 80 km/hr the driver suddenly notices another slower car ahead, a distance d = 50 m ahead, moving at 30 km/hr. At this moment, in order to avoid hitting the slow-moving car ahead the driver slows down but takes .25 seconds to react relative to first noticing the car 50 m ahead. Assuming the car decelerates at a constant rate, above what minimum magnitude of the deceleration avoids a rear-end collision? can you solve this with a detailed explanation
