You are arguing over a cell phone while trailing an unmarked police car by 26.0 m. Both your car and the police car are traveling at 102 km/h. Your argument diverts your attention from the police car for 2.50 s (long enough for you to look at the phone and yell, "I won't do that!"). At the beginning of that 2.50 s, the police officer begins emergency braking at 5.00 m/s².

(a) What is the separation between the two cars when your attention finally returns?
m

(b) Suppose that you take another 0.400 s to realize your danger and begin braking. If you too brake at 5.00 m/s², what is your speed when you hit the police car?
km/h
