The police officer in car P observes this speed via radar. The driver ofcar A sees and reacts very unwisely to the police car P. Car A is traveling at VA = 127 km/h as it passes P, but over the next 5.7 seconds,the car uniformly accelerates to 154 km/h, after which that speed is maintained. At the moment when A passes P, the police car beginsto accelerate at the constant rate of 5.6 m/s2 until a speed of 169 km/h is achieved, and that speed is then maintained.
