A man strikes one end of a thin rod with a hammer. The speed of sound in the rod is 18 times the speed of sound in air. A woman, at the other end with her ear close to the rod, hears the sound of the blow twice with a 0.13 s interval between; one sound comes through the rod and the other comes through the air alongside the rod. If the speed of sound in air is 346 m/s, what is the length of the rod?

There is a person, he strikes one end of a metal rod with a hammer. We have another person at the end of the rod feels a vibration in the rod 0.195 s before he hears the hammer strike the rod. If the temperature is 23◦C, how long is the metal rod? Use a bulk’s modulus of 106 GPa and a density of 5.69 g/cm3 .

006 10.0 points A copper rod is given a sharp compressional blow at one end. The sound of the blow, traveling through air at -3.43 °C, reaches the opposite end of the rod 6.2 ms later than the sound transmitted through the rod. What is the length of the rod? The speed of sound in copper is 3780 m/s and the speed of sound in air at -3.43 °C is 331 m/s. Answer in units of m.

A hammer taps on the end of a 3.90-m-long metal bar at room temperature. A microphone at the other end of the bar picks up two pulses of sound, one that travels through the metal and one that travels through the air. The pulses are separated in time by 10.8ms .What is the speed of sound in this metal? Vmetal =.........m/s

For testing purposes, a musical instrument manufacturing company creates a device so that when you blow into one end with your instrument, sound comes out the other end in opposite directions. A sound technician uses a whistle and generates sound waves with a frequency of 226 Hz. The waves travel in opposite directions in a sound studio, are reflected by end walls, and return. The studio is 42.0 m long and the whistle is located 14.0 m from one end....

The diagram shows a thin rod of uniform mass distribution pivoted about one end by a pin passing through that point. The mass of the rod is 0.290 kg and its length is 1.30 m. When the rod is released from its horizontal position, it swings down to the vertical position as shown. Determine the speed of its center of gravity at its lowest position. m/s When the rod reaches the vertical position, calculate the tangential speed of the free...
