You are arguing over a cell phone while trailing an unmarked police car by 32 m. Both your car and the police car are traveling at 100 km/h. Your argument diverts your attention from the police car for 1.5 s (long enough for you to look at the phone and yell, "I won't do that!"). At the beginning of that 1.5 s, the police officer begins emergency braking at 5 m/s2.
