Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. The driver of car A sees and reacts very unwisely to the police car P. Car A is traveling at VA = 125 km/h as it passes P, but over the next 5.2 seconds, the car uniformly accelerates to 147 km/h, after which that speed is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.1 m/s² until a speed of 175 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. A Answer: s= i VA P m
