You are arguing over a cell phone while trailing an unmarkedpolice car by 25.0 m; both your car and the police car aretraveling at 110 km/h. Your argument diverts your attention fromthe police car for 2.0 s (long enough for you to look at the phoneand yell,“I won't do that!â€). At the beginning of that 2.0 s, thepolice officer begins braking suddenly at 5.20 m/s2.(a) What is the separation between the two carswhen your attention finally returns? Suppose that you take another0.400 s to realize your danger and begin braking.(b) If you too brake at 5.20 m/s2, whatis your speed when you hit the police car?
