A person is riding a motorcycle at a speed v towards a stationary car operating its siren at Hz. A police car is chasing the person at a speed 22 m/s with its siren operating at 176 Hz. If the motorcyclist does not heard beats, the speed v (m/s) is (speed of sound in air = 330 m/s)

zero

Text Solution

Verified by Experts

`(165(330+v))/330=176(330/(330-22))`
