6. In order to be able to determine her speed, a skydiver carries a tone generator. A friend on the ground at the landing site has equipment for receiving and analyzing sound waves. While the skydiver is falling at terminal speed, her tone generator emits a steady tone of 753 Hz. Assume: The air is calm and that the sound speed is 343 m/s, independent of altitude. If her friend on the ground (directly beneath the skydiver) receives waves of frequency 2260 Hz, what is the skydiver's speed of descent? [ANS: 228.717 m/s.]
