Textbook Question
Chapter 3, Problem 20Q
If you are riding on a train that speeds past another train moving in the same direction on an adjacent track, it appears that the other train is moving backward. Why?
This is a question of relative velocity. From the point of view of an observer on the ground, both trains are moving in the same direction (forward), but at different speeds. From your point of view on the faster train, the slower train (and the ground) will appear to be moving backward. (The ground will be moving backward faster than the slower train!)

An ultrasound doppler meter is used to detect motion for an alarm system. The unit
emits an ultrasound signal and its echo is detected back at the same unit. If the unit
emits a frequency of 100 MHz and is only able to detect a change in frequency of the
reflected sound greater than 8.0 kHz, what is the maximum speed that an intruder
can travel at relative to the unit whilst remaining undetected? Take the speed of
sound in air to be 343 m/s.

- Car A is traveling at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. The driver of car A sees and reacts very unwisely to the police car P. Car A is traveling at VA = 125 km/h as it passes P, but over the next 4.4 seconds, the car uniformly accelerates to 153 km/h, after which that speed is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.8 m/s² until a speed of 168 km/h is achieved, and that speed is then maintained.
