If a sound with frequency f, is produced by a source traveling along a line with speed ve and an observer is traveling with speed v, along the same line from the opposite direction toward the source, then the frequency of the sound heard by the observer is fo where c is the speed of sound, about 332 m/s. (This is the Doppler effect.) Suppose that, at a particular moment, you are in a train traveling at 44 m/s and accelerating at 1.6 m/s2. A train is approaching you from the opposite direction on the other track at 48 m/s, accelerating at 1.9 m/s2, and sounds its whistle, which has a frequency of 428 Hz. At that instant, what is the perceived frequency that you hear? (Round your answer to one decimal place.) Hz How fast is it changing? (Round your answer to two decimal places.) Hz/s

There was an accident and NASA engineers are trying to sort out where two of their Mars Rovers, Tango and Foxtrot, have landed. The engineers know that landing site A is much hotter than landing site B. Unfortunately, the only working sensors on Tango and Foxtrot measure the speed of sound. If Tango measures the speed of sound at it's landing site as 240 m/s, while Foxtrot measures speed of sound as 258 m/s at it's landing site, where has each rover landed?
A tourist at a rim of a canyon yells "hello!" toward the opposite side. She hears the echo "hello" four seconds later. If the speed of sound is 340 m/s, how far did the echo travel?
A source of sound of frequency 1200 Hz is moving away from a listener at speed v. The listener is at rest and hears a frequency of 1150 Hz. Given that the speed of sound is 343 m/s, what the value of v? 15 m/s 20 m/s 25 m/s 30 m/s 35 m/s
14. An astronaut is flying in a spaceship with a speed of 0.8 c with respect to Earth. The astronaut observes an event on Earth and determines that the time interval for the event to be completed is 33 hours. a) If the astronaut had a speed of 0.93 c with respect to Earth, what would she observe the time interval to be for that same event? b) Would the astronaut measure the proper time interval or the dilated time interval? Justify your response.
A nuclear power reactor generates 3.00 x 10^9 W of power. In one year, what is the change in the mass of the nuclear fuel due to the energy conversion? (A 1 W power source gives 1 J/s)
A particle is traveling at 0.98c, where c is the speed of light. According to an observer at rest, the particle is traveling a distance 5.6 meters before disintegrating. What is the lifetime of the particle as measured in the moving frame? Express your answer in nanoseconds and keep three significant digits
As you zip through space in your PPS (personal propulsion suit), your pulse rate as you count it is 117 bpm (beats per minute). This high pulse rate serves as objective evidence of your excitement. However, an observer on the Moon, an expert in pulse rate telemetry, measures your pulse rate as slower. In fact, she detects only 0.525 times the rate you count and claims that you must be pretty calm in spite of everything that is going on. How fast are you moving with respect to the Moon? m/s speed relative to the Moon:
Three digital clocks A, B, and C run at different rates and do not have simultaneous readings of zero. The figure shows simultaneous readings on pairs of clocks for four occasions. (At the earliest occasion, for example, Breads 25.0 s and C reads 92.0 s.) If two events are 500 s apart on clock A, how far apart are they on (a) clock B and (b) clock C? (c) When clock A reads 380 s, what does clock B read? (d) When clock C reads 10 s, what does clock B read? (Assume negative readings for pre-zero times.)
Light travels at a speed of about 3×10; m/s. How many miles does a pulse of lighttravel in a time interval of 0.1s? (1 mile = 1609 m)?
A tourist at a rim of a canyon yells "hello!" toward the opposite side. She hears the echo "hello" four seconds later. If the speed of sound is 340 m/s, how far away was the canyon wall that produced the echo?
Someone in Earth's rest frame says that a spaceship's trip between two planets took 10.0 years, while an astronaut on the space ship says that the trip took 6.27 years. Find the speed of the spaceship (as measured by someone in Earth's rest frame) in terms of the speed of light. 0.959c 0.687c 0.489c 0.684c 0.779c
