Tim is standing at a bus stop when two cyclists traveling in the same direction toward him are each blasting a radio with sound of a single frequency. Each cyclist is traveling at 4.68 m/s and as the first cyclist passes him but before the second cyclist does, Tim hears a beating frequency of 4.04 Hz. What is the frequency of the sound played by the cyclists? Use the speed of sound of 343 m/s in air. Number Units

Repeat this problem, but assume the ambulance and car are going the same direction, with the ambulance initially behind the car. The speeds and the frequency of the siren are the same as in the example. Find the frequency heard by the observer in the car (a) before and (b) after the ambulance passes the car. Note: The highway patrol subsequently gives the driver of the car a ticket for not pulling over for an emergency vehicle! Ambulance speed: 75...

An ambulance sounding its siren with a frequency of 1550 Hz is traveling along a straight road with a speed of 34 m/s. Two cars are ahead of the ambulance in an adjacent lane. One car has completely stopped. A second car continues to travel in the same direction as the ambulance with a speed of 20 m/s. (a) Which of the two cars hears the highest pitch coming from the ambulance? Explain. (b) Suppose the driver of the stationary...

Two trains are traveling on the same track and in the same
direction. The first train, which is behind the second train, blows
a horn whose frequency is 269 Hz. The second train detects a
frequency of 290 Hz. If the speed of the second train is 13.7 m/s,
what is the speed of the first train?
