ANSWER:

Solution 76P Let us have a look at the figure below to understand the situation given in the question. Angular velocity = 2f p Amplitude of vibration = A p Linear velocity of the platform with the siren is v = A 2f p p v = 2A f p p Let us now calculate the frequencies in each case during the vibration of the system. (a) When the siren a
