A train is moving pass a crossing where cars are waiting for it to pass. While waiting, the driver of the lead car becomes sleepy and rests his head on the steering wheel, unintentionally activating the car's horn. A passenger in the back of the train hears the horn's sound at a frequency of 444 Hz and a passenger in the front hears it at 415 Hz. Find the train's speed and the horn's frequency, assuming the sound travels along...

A train: A enters a train station with constant speed of .00 m/s while another train B leaves the train station with constant speed of 4.00 m/s. At a moment they are both at the same distance of 1 km from the train station they whistle two identical sounds of 400. Hz with acoustic power of 70.0 W each. A passenger standing on the station platform. No wind is blowing. (a) What is the frequency of the sound from A...

Two passenger trains are moving towards each other with the speeds of 45 km/hr each. Each train is of 250m length. The conductors in the last carriages of the trains are sitting in the backs of the carriages. How much time will pass between the meeting of the two engineers to the meeting of the two conductors?

Two trains approach each other on separate but adjacent tracks. Train 1 is traveling at a speed of 35.9 m/s and train 2 at a speed of 27.6 m/s. If the engineer of train 1 sounds his horn which has a frequency of 520 Hz, determine the frequency of the sound heard by the engineer of train 2. (Use 343 m/s as the speed of sound. Enter your answer to the nearest Hz.)

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?
I used the following equation and set Fo to 290Hz and Fs to
269hz. + on top and - on bottom. I figured...

A siren, attached to a parked car, emits a sound with frequency 960 Hz. You are driving in your car, either straight towards or straight away from the parked car, and hear a frequency of 1069 Hz. Are you moving towards or away from the car? towards away How fast must you be moving? (Give your answer rounded to two sigfigs.)40

Two trains on separate tracks move toward each other. Train 1 has a speed of 113 km/h; train 2, a speed of 59.0 km/h. Train 2 blows its horn, emitting a frequency of 500 Hz. What is the frequency heard by the engineer on train 1? Hz A person wears a hearing aid that uniformly increases the intensity level of all audible frequencies of sound by 30.7 dB. The hearing aid picks up sound having a frequency of 250 Hz...

9. An ambulance truck emits a sound with a frequency of 800 Hz. (the speed of sound in air at 20 Celsius is 343 m/s). (a) What is the frequency detected by a stationary observer if the ambulance truck moving 30 m/s toward the observer? (b) What frequency will b detected if the ambulance is moving 30 m/s away from the observer?

erixx Initially, trains A and B are 325 miles away from each other. Train A is traveling towards B at 50 miles per hour and train B is traveling towards A at 80 miles per hour. At what time will the two trains meet? At this time how far did the trains travel? Create a system of linear equations that model the problem situation. Identify the variables. • Solve the system to determine the answer. • Explain your reasoning.
