A police car moving at 22m//s , chases a motorcyclist, the police man sounds his horn at 176 Hz , while both of them move towards a stationary siren of frequency 165 H z. Calculate the speed of the motorcycle, if it is given that he does not observes any beat

A police car moving at 22 m//s , chase a motoclist. The police man has horn at 176 H_(Z) , While both of them move towards a stationary siran of frequency 165 H_(Z) . Calulate the speed of the motorcyclist, if he does not observer any beats. (velocity of sound in air = 330 m//s)

A police car moving at 22 ms^(-1) chases a motor cyclist. The police man sounds horn at 176 Hz. While both of them move towards a stationary siren of frequency 165 Hz. If the number of beats heard by the motor cyclist per second is zero, then the speed of motorcycle is (Speed of sound in air = 330 ms^(-1) )

A police car moving at "30 m s"^(-1) , chases a motorcyclist. The policeman sounds his horn at 180 Hz, while both of them move towards a stationary siren of frequency 160 HZ. He does not observe any beats then, calculate the speed ("in m s"^(-1)) of the motorcyclist round off two decimal places? [speed of sound =330ms^(-1) ]
