10. [5.05/17 Points] DETAILS PREVIOUS ANSWERS DOPPLER: Reflection and Echoes #2 The dog is barking at frequency, fdog = 5.7 KHz, at a delivery truck that is driving directly away from it at speed, v = 8.8 m/s, as shown in the figure. Assume that the speed of sound in air is 350 m/s, and round your answers to the nearest 1 Hz. 1. What Does the Driver Hear? The driver is a | moving observer so you should use: ofo = Sidog ofo = dog ofo = ( c t vidog . fo = ( c - vidog C +v C C ofo = fdog The barks heard by the driver have a frequency of 40 5847.010 hz . x The | single * doppler shift is therefore 5847 Hz X Which equation would you use to calculate the simplified doppler shift? ofD = +ofdog off = + Video of = -idea ofp = -Vidog The simplified doppler shift is therefore Submit 2. Frequency of the Echoes (1 of 3) The dog hears the echoes of its barks reflected off the moving truck. The truck is the moving source of the echoes. The source frequency for the echoes is therefore fecho = 405 Submit
