Question
Chapter 15, Problem 31A
To determine
The shape of an emblem on a fast-moving rocket ship.
Expert Solution & Answer
Answer to Problem 31A
It is elliptical to the observers on the rocket ship.
Explanation of Solution
Introduction:
According to the length contraction phenomenon, the length of the moving objects looks shorter than actual to the stationary observers.
Rocket ship will be in the shape of an ellipse with the major axis facing the direction of motion. It is because when the rocket moves forward, then due to length contraction major axis shortens and looks equal to the unperturbed minor axis. This will create a perception of looking circular emblem on the rocket ship.
Conclusion:
Thus, if length contraction is neglected then the shape of the emblem on the rocket ship is elliptical in real.

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?
