The equation for the Doppler shift of a sound wave of speed v, reaching a moving detector, is where vd is the speed of the detector; vs is the speed of the source; f is the frequency of the source; f' is the frequency at the detector. If the detector moves toward the source, vd is positive; if the source moves toward the detector, vs if positive. A train moving toward a detector at 35 m/s blows a 303-Hz horn. What frequency is detected by a (a) stationary train
