Transcribed Image Text: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 = 128 km/h as it passes P, but over the next 4.3 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 4.5 m/s? until a speed of 157 km/h is achieved, and that speed is then maintained. Determine the distance s required for the
police officer to overtake car A.
