Answer:
The velocity of the truck is
The velocity of the car is
Step-by-step explanation:
From the question we are told that
The natural frequency of a truck horn is
The apparent frequency of the truck horn is
The relative speed is
Generally the relative speed when the truck and the car are moving towards each other is
Here
are the velocities of the truck and the car respectively
=>
Generally the apparent frequency is mathematically represented as
Here v is the speed of sound with value
=>
=>
=>
From the above equation we have that
=>
=>
