You are traveling at 38m/s toward oncoming car traveling at 28m/s toward you. Just before it reaches you, the car honks its horn at you. The frequency of the horn is 365Hz. What is the change in frequency of the horn as the car passes you?
This is possibly a different atmosphere from ours. In any case, the speed of sound is computer-generated, and is 454 m/s this time. Light travels for us instantaneously. You see a lightning flash, and 7.6 seconds later, you hear the thunderbolt. How far away was the lightning (in meters)?
A person holds a rifle horizontally and fires at a target. The bullet leaves the muzzle of the rifle with a velocity of 460m/s. Two seconds later the person hears the bullet strike the target. If the speed of sound in air is 340 m/s, calculate the distance travelled from the bullet to the target.
An explosion occurs at the end of a pier. The sound reaches the other end of the pier by traveling through three media: air, fresh water, and a slender metal handrail. The speeds of sound in air, water, and the handrail are 346, 1400, and 5480 m/s, respectively. The sound travels a distance of 142 m in each medium. (a) After the first sound arrives, how much later does the second sound arrive? (b) After the first sound arrives, how much later does the third sound arrive? (a) Number i (b) Number i Units Units
You are standing on a train station platform as a train goes by close to you. As the train approaches, you hear the whistle sound at a frequency of f1 = 94 Hz. As the train recedes, you hear the whistle sound at a frequency of f2 = 77 Hz. Take the speed of sound in air to be v = 340 m/s. Find an equation for the speed of the sound source vs, in this case it is the speed of the train. Express your answer in terms of f1, f2, and v. Find the numeric value, in meters per second, for the speed of the train. Find an equation for the frequency of the train whistle fs ("s" is for "source") that you would hear if the train were not moving. Express your answer in terms of f1, f2, and v.

An enormous thunderstorm covers Dallas-Ft. Worth. Your best friend Clark is a storm chaser and heads to the center of the storm to take some readings while you stay dry at home. While Clark is at the center of the storm, he sees and hears lightning strike a tree that is 185 m from where he is standing. You are 134 km from the tree. How long does it take for the sound to reach Clark? Assume the speed of sound is 343 m/s. How long does it take for the light to reach you?
