1. You are arguing over a cell phone while trailing an unmarked police car by 34 m. Both your car and the police car are traveling at 105 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 emergency braking at 5 m/s2. (a) What is the separation between the two cars when your attention finally returns? (Hint: This problem might be a bit easier to solve using the idea of relative velocity.) m (b) Suppose it takes you another 0.4 s to realize your danger and begin braking. If you too brake at 5 m/s2, what is your speed when you hit the police car? km/h How much time passes between your initial braking and the collision? s How much distance do you cover during this time (i.e., while braking)?
