I was wondering if anyone could help me with part b of this question. You are arguing over a cell phone while trailing an unmarked police car by 28m; both your car and the police car are traveling 110km/h (about 31m/s). You take your eye off the road for 2.0s because of the argument. At the very beginning of the 2.0s, the police car brakes at 5m/s^2. a) what is the separation between the two cars when your attention returns? I already got this right, its 18 meters. b) Suppose you take another .40s to realize the danger and begin braking. If you too brake at 5m/s^2, what is your speed when you hit the police car? For this I have solved for the velocity of the police car after it has been braking for 2.4s (15.7778 m/s). The velocity of my car is still 27.7778m/s. And the seperation distance is now 14.3999m after the 2.4 s. I am confused on where to go at this point with the question. If anyone could help me that would be great. Thanks.
