Inside Biker Bob’s space station is a ladder that extends from the inner surface of the rim to the central axis. Bob climbs the ladder (toward the center). Point A is at the floor, point B is halfway to the center, and point C is at the central axis.
a. Rank the linear speeds of Bob relative to the center of the station, from highest to lowest. Or are the speeds the same at all parts of the ladder?
b. Rank the support forces Bob experiences on the ladder rungs, from greatest to least. Or are the support forces the same in all locations?
(a)
To rank: The linear speed of person B relative to the center of the station.
Answer to Problem 17A
A> B> C.
Explanation of Solution
Introduction:
Artificial gravity is activated inside the space station to have stability and no collisions due to free fall. The more the distance, the less gravitational force will be experienced.
Artificial gravity will be experienced maximum on the floor. Thus, B’s linear speed is maximum at the inner surface of the rim.
Now, at halfway to the central axis, acceleration due to gravity will be half value of the former. So, the linear speed is half.
Now, at the central axis, gravity will be null. Hence, B will have no linear speed here i.e. zero motion.
Conclusion:
Thus, the linear speed of the B relative to the center of the station would be highest at the floor then it would be intermediate at the halfway to the center, and then it would be lowest, as it is reaching towards the Central axis. The rank is A> B> C
(b)
To rank: The support forces person B experiences on the ladder rungs from greatest to least.
Answer to Problem 17A
A > B > C
Explanation of Solution
Introduction:
Artificial gravity is activated inside the space station to have stability and no collisions due to free fall. The more the distance, the less gravitational force will be experienced.
Support forces would vary from the central axis as per the value of acceleration due to gravity “g”. At the floor that is, at the inner surface of the rim, g will be maximum. Thus, support forces would be maximum at the inner surface of the rim.
Since B is at halfway to the central axis, the value of acceleration due to gravity would be half of it was at point “A” leads to half of the support forces at point “A”.
At last, at the central axis value of acceleration due to gravity reaches to zero. Thus, no support forces will be experienced at the central axis.
Conclusion:
Thus, Support forces vary from inner surface to the central axis as

- 13.87 ... 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?
