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 is traveling at VA = 122 km/h as it passes P, but over the next 4.1 seconds, the car uniformly decelerates to the speed limit of 100 km/h, and after that the speed limit is maintained. 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 164 km/h is achieved, and that speed is then maintained. Determine the distance s required for the police officer to overtake car A. Answer: s= i VA 248.52 P m
