You are arguing over a cell phone while trailing an unmarked police car by 26 m; both your car and the police car are traveling at 120 km/h. Your argument diverts your attention from the police car for 2.0 s (long enough for you to look at the phone and yell,"I won't do that!"). At the beginning of that 2.0 s, the police officer begins braking suddenly at 5.00 m/s². (a) What is the separation between the two cars when your attention finally returns? Suppose that you take another 0.400 s to realize your danger and begin braking. (b) If you too brake at 5.00 m/s², what is your speed when you hit the police car?
