Answer:
T1 = 250.57[N] and T2 = 250.57[N]
Explanation:
First we have to extract all the information they give us about the problem, then make a free body diagram with all the forces that act on the body.
In the attached image we can see the free body diagram with the respective forces.
By summing up forces on the Y-axis, we can find the T1 and T2 force, these forces are equal since it is an initial condition of the problem. This equation can therefore be cleared.
The equations and analysis can be seen in the attached image

Answer:
d). The value of y should be -32m
Vx=0.92 m/s
Explanation:
Using equation of motion uniform to y motion
So to find t that is the same time for all the motion
The value of Xf=-3.2m because the g is negative from the axis
Now in the axis 'x' to find Vx
Answer:
Time period for first satellites 24.46 days and for second satellites 37.67 days
Explanation:
Given :
Distance of first satellites m
Distance of second satellites m
Distance of charon m
Time period of charon days
From the kepler's third law,
Square of the time period is proportional to the cube of the semi major axis.
For first satellites,
days
For second satellites,
days
Therefore, time period for first satellites = 24.46 days and for second satellites 37.67 days
