A police car waits in hiding slightly off the highway the highway. A speeding car is spotted by the police car doing 40 m/sec. At the instant the speeding car passes the police car, the police car accelerates from rest at 4 m/sec² to catch the speeding car. The speed of the speeding car remains constant. a) How long does it take the police car to catch the speeding car? Answer: 20 sec b) What distance does the police car need to travel to catch the speeding car? Answer: 800 m. Car 1, Speeding Car Xo = 0 Vo = 40 m/sec a 0 m/sec² (constant speed) Car 2, Police AY X = 0 m Vo = 0 m/sec a = 4 m/sec²
