Answer:
Follows are the solution to this question:
Explanation:
By checking the value in which we have calculated by performing its differentiation of
, the correct form of its integer value is calculating with regard to t, that also provides as expected
.
Answer: 
Explanation:
The rest of the question is below:
Find a2, the magnitude of the centripetal acceleration of the star with mass m2.
Assuming both stars are describing a uniform circular motion, their acceleration vector is directed towards the center of mass of the system (that's why it's called centripetal acceleration).
Now, according to Newton's 2nd law, the force
is directly proportional and in the same direction as the acceleration.
For
:
For
:
If the centripetal force is the same for both stars:
