You are arguing over a cell phone while trailing an unmarked police car by 32 m. Both your car and the police car are traveling at 110 km/h. Your argument diverts your attention from the police car for 2.5 s (long enough for you to look at the phone and yell, "I won't do that!"). At the beginning of that 2.5 s, the police officer begins emergency braking at 5 m/s2. (a) What is the separation between the two cars...
An unmarked police car traveling a constant 95 km/h is passed by a speeder traveling 140 km/h. Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 2.60 m/s2 , how much time passes after the police car is passed by a speeder and before the police car overtakes the speeder (assumed moving at constant speed)? Express your answer with the appropriate units.
An unmarked police car traveling a constant 95 km/h is passed by a speeder traveling 130 km/h. Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 2.50 m/s^2, how much time passes after the police car is passed by a speeder and before the police car overtakes the speeder (assumed moving at constant speed)?
An unmarked police car traveling a constant 85 km/h is passed by a speeder traveling 136 km/h . Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 2.30 m/s2 , how much time passes after the police car is passed by a speeder and before the police car overtakes the speeder (assumed moving at constant speed)?

Krishna and Seldon now try a homework problem. A policeman sitting in his unmarked police car sees an approaching motorcyclist go through a red light two blocks away. He turns on his siren at a frequency of 1000 Hz as the motorcyclist heads directly toward him at 51 mph (22.80 m/s). What frequency does the motorcyclist hear? (Enter your answer to at least the nearest integer. Assume the speed of sound in air is 331 m/s.) What frequency does the...
I'm driving down the highway in my car, at a speed of 25 m/s. Some jerk cuts me off and rapidly slows down, so I have to slam on my brakes to avoid hitting him. (a) If I brake for 5.0 s down to a speed of 15 m/s, what was my acceleration during that period? You may assume that my acceleration was constant. (b) What distance did I travel during the period in which I was braking?
