Tuning Fork The end of a tuning fork moves in simple harmonic motion described by the equation d= asin(wt). If a tuning fork for the note E above middle C on an even­ tempered scale (E4) has a frequency of approximately
329.63 hertz (cycles per second), find w. If the maximum dis­
placement of the end of the tuning fork is 0.025 millimeter, determine the equation that describes the movement of the tuning fork.
