- During a 4th of July celebration, an M80 firework explodes on the ground, producing a bright flash and a loud bang. The air temperature of the night air is TF=90.00F . Two observers see the flash and hear the bang. The first observer notes the time between the flash and the bang as 1.00 second. The second observer notes the difference as 3.00 seconds. The line of sight between the two observers meet at a right angle as shown below. What is the distance x between the two observers?arrow_forwardOn a particular day the speed of sound in air is 340 m/s.

- A train is moving past 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 cars horn. A passenger in the back of the train hears the horns sound at a frequency of 428 Hz and a passenger in the front hears it at 402 Hz. Find (a) the trains speed and (b) the horns frequency, assuming the sound travels along the tracks.arrow_forwardAn airplane is flying at Mach 1.50 at an altitude of 7500.00 meters, where the speed of sound is v=343.00 m/s.
