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
