Question
A model for the vibrations of a wine glass is x + Ax +w²x = 0. Assume that when the glass is struck it vibrates at 660 Hz. a) Show that 4w2 – X² = 2640r. b) If the sound takes about 3 seconds to disappear, and this happens when the original vibrations have been reduced to 1/ 100 from their initial level, show what 2 In 100 3
