A police car moving at 22 m/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 Hz. Calculate the speed of the motorcycle, if it is given that he does not observes any beats
(1) 33 m/s
(2) 22 m/s
(4) 11 m/s
(2) n1 = Frequency of the police car horn observer heard by motorcyclist
n2 = Frequency of the siren heard by motorcyclist.
v2 = Speed of motor cyclist
