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 approximately329.63 hertz (cycles per second), find w. If the maximum displacement of the end of the tuning fork is 0.025 millimeter, determine the equation that describes the movement of the tuning fork.
An object acted on by three forces moves with constant velocity. One force acting on the object is in the positive x direction and has a magnitude of 6.6N; a second force has a magnitude of 5.0N and points in the negative y direction. Discover the ma..
