What is the frequency of the sound heard by the driver of car B from car A?

Question Parameters:

A car moves at 72 km/h and car B moves at 90 km/h, approaching each other. A car honked with a frequency of 650 Hz

the speed of the sound waves in the air is 350 m/s,

Generally, the equation for the Frequency   is mathematically given as

[tex]F=f'(\frac{v+vob}{v-vsource})[/tex]

Therefore

[tex]F=650(\frac{350+25}{350-20})[/tex]

F=738.6hz

In conclusion, the frequency of the sound is

F=738.6hz
