9. A car is traveling on the highway at a constant speed of 24m/s. The driver misses the posted speed limit sign for a small town she is passing through. The police car accelerates from rest at 2.1 m/s². From the time that the speeder passes the police car: How long will it take the police car to catch up to the speeder? What distance will the car travel in that time? [23s, 5.5 x 10²m]
