One of two identical 500-Hz tuning forks is at rest and other is moving. These produce a beat frequency of 5 Hz.
(a) What are the possible velcities of the moving fork?
(b) Do you have enough information to determine wether the moving fork moves towards or away from the stationary fork. What additional information, if any, might be useful in this determination?
