Chapter 25, Problem 50A
Does a boat moving through the water always produce a bow wave? Defend your answer.
Expert Solution & Answer
To determine
To check: Whether a boat moving through the water always produces a bow wave.
Answer to Problem 50A
Not always, only when the speed of the boat increases the speed of the waves.
Explanation of Solution
Introduction: A bow wave is produced when the source propagates faster than the waves it produces.
When a boat moves away in the water, then it produces waves in the water left behind. If the boat moves faster than those waves then it generates a shock producing bow waves.
If the speed of the boat is less than the waves it produced, then the waves will not overlap and bow waves will not produce.
Conclusion: Thus, bow waves are produced only when the speed of the boat is greater than the waves, it is producing.

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? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets?
