Newton's Law of Gravitation states that two bodies with masses m1 and m2 attract each other with a force F, where r is the distance between the bodies and G is the gravitational constant.

F=G m1m2/r2

Use Newton's Law of Gravitation to compute the work W required to propel a 1400 kg satellite out of the earth's gravitational field. You may assume that the earth's mass is 5.98✕1024 kg and is concentrated at its center. Take the radius of the earth to be 6.37✕106 m and G = 6.67✕10-11 Nm2/kg2. (Round your answer to three significant digits.)

The workdone is  

Explanation:

From the question we are told that

    The equation for the force is  

     The gravitational constant is

     The mass of satellite is  

      The radius of the earth is  

        The mass of earth is  

Generally the work required is mathematically represented as

Where  b =  G this is because the satellite has to overcome the earth gravitational pull

 And  a  =    this because at infinity the there is not effect of gravitational force

        So

  substituting values

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
