If we view a passing spaceship and see that the inhabitants' time is running slow, how do they see our time running?
To explain: The condition of running time seen by inhabitant.
Answer to Problem 9A
They will see our time running slow too.
Explanation of Solution
Introduction: According to the special theory of relativity, the speed of light is constant in each inertial frame.
In both of the frames, time will run at the same speed. But, when seen from other inertial frames then distance to which light travels from one inertial frame to another adds with the time of the first inertial frame.
Conclusion: Thus, when seen from the second inertial frame time in the first inertial frame runs slow.

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? 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? (c) To reach Mars from the…arrow_forward
