this is the Doppler effect (google it)
the pitch (frequency) is higher because you are moving toward the source
f = [343 / (343 - 5)] * 4000
Please help me... I have no idea where to begin...A tone of 4000 Hz is being played on a tuning fork. You run toward the tuning fork at 5 m/s. What frequency do you hear? Take the speed of sound to be 343 m/s.
