<h3>Can galaxies recycle stars?</h3>
Galaxies do not appear to have sufficient matter inside them to keep shaping modern stars at the rates that they do. Presently, astronomers have caught a universe within the act of reusing fabric that it already tossed out, which may clarify the discrepancy. New perceptions give the primary coordinate evidence of gas streaming into distant galaxies that are effectively making infant stars, offering support for the "galactic recycling" theory.

To solve this problem it is necessary to use the concepts related to the Gravitational Force and Newton's Second Law, as far as we know:

Where,
G = Gravitational constant
M = Mass of earth (in this case)
m = mass of satellite
r = radius
In the other hand we have the second's newton law:

Where,
m = mass
a = acceleration
Equation both equations we have,

For the problem we have that,
<em>Satellite A:</em>

<em>Satellite B:</em>

The ratio between the two satellites would be,

Solving for a_B,

Therefore the centripetal acceleration of
is a quarter of 
Answer:
around 50 miles per hour is the answer i believe :)
