Textbook Question
Chapter 14, Problem 82P
An airport neighborhood is concerned about the basing of the new F-35 jet fighter. They’ve got the data below for the sound intensity level measured at different distances from the plane as it takes off. They’d like to know the total sound power emitted by the plane. As a physics student, you’re called to help. First, convert the sound intensity levels to actual intensity. Then find a quantity which, when you plot intensity against it, should give a straight line. Make your plot, determine the best-fit line, and use its slope to report the total sound power.
| Distance (m) | 1000 | 1200 | 1500 | 2000 | 3000 | 4000 |
| Sound intensity level (dB) | 80.7 | 79.4 | 76.9 | 74.2 | 71.6 | 68.8 |

Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion?
