Skills for analyzing processes involving vibrational motion
Annoying sound Low-frequency vibrations (less than 5 Hz) are annoying to humans if the product of the amplitude and the frequency squared (Af 2) equals 0.5 x 10-2 m . s-2 (or more). Estimate the frequency and amplitude of a buzzer that produces these annoying vibrations if the device vibrates a total mass of 0.12 kg and has a vibrational energy of 0.012 J.
