A hunter is standing on flat ground between two vertical cliffs that are directly opposite one another. He is closer to one cliff than the other. He fires a gun and, after a while, hears three echoes. The second echo arrives 1.65 s after the first, and the third echo arrives 1.18 s after the second. Assuming that the speed of sound is 343 m/s and that there are no reflections of sound from the ground, find the distance (in m) between the cliffs.

A hunter is standing on flat ground between two vertical cliffs that are directly opposite one another. He is closer to one cliff than the other. He fires a gun and, after a while, hears three echoes. The second echo arrives 1.35 s after the first, and the third echo arrives 1.09 s after the second. Assuming that the speed of sound is 343 m/s and that there are no reflections of sound from the ground, find the distance (in...
On a hiking trip, you are walking through a canyon with vertical walls and are closer to one wall than the other. Having taken Physics, you decide to determine the width of the canyon by using your knowledge of kinematics and the speed of sound. You shout "Hey" as loud as you can, and after a short time you hear three echoes. The second echo arrives 1.5 safter the first, and the third echo arrives 0.9 s after the second....
In a scene from the movie 'Matrix Reloaded', Trinity (one of the 'good characters') is falling out a high window towards the ground with agent Johnson (a 'bad guy') falling out of the window towards her. (The agent falls from the window after Trinity does, so the agent is above (further from the ground) than Trinity.) While falling, Trinity fires her gun upwards at the agent. Let's make the following assumptions: Trinity's speed towards the ground is 54 m/s (she...
You are standing somewhere between Anderson Hall and Ahearn Field House when the loud bells in Anderson Hall Tower toll. After each bell from Anderson, there is an echo from Ahearn 6.00 s later. How far are you from Ahearn? Use 343 m/s for the speed of sound.
1-5 test prep please help Waves A fisherman notices that wave crests pass the bow of his anchored boat every 3.0 s. He measures the distance between two crests to be 6.5 m. How fast are the waves traveling? 2. A sound wave in air has a frequency of 262 Hz and travels with a speed of 343 m/s. How far apart are the wave crests (compressions)? io signals have frequencies between 550 kHz and 1600 kHz and travel with...
.Please form info discussion groups of 3 (no more than 3) to solve the following questions. Use the boards in the classroom to discuss the details of your solutions and show of work. Markers and erasers will be provided. Please return them after end of the class. Groups will be called to solve the questions for the rest of the class (bonus points opportunity) The final answers to each question is provided in the parenthesis. You need to arrive at...
