Question

You are arguing over a cellponone while trailing an unmarked police car by 27 m. Both your car and the police car are traveling at 105 km/h. Your argument diverts your attention from the police car for 1.5 s (long enough for you to look at the phone and yell, "I won't do that!"). At the beginning of that 1.5 s, the police officer begins emergency braking at 5 m/s²

Other known values:

The separation between the two cars when your attention finally returns is 21.37 m.

Suppose it takes you another 0.4 s to realize your danger and begin braking. If you also brake at 5 m/s², your speed when you hit the police car is 70.81 km/h.

(a) How much time passes between your initial braking and the collision?

(b) How much distance do you cover during this time (i.e., while braking)?
