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 m1*m2/r^2
use newton's law of gravitation to compute the work w required to propel a 800 kg satellite out of the earth's gravitational field. you may assume that the earth's mass is 5.98 x 10^24 kg and is concentrated at its center. take the radius of the earth to be 6.37 x 10^6 m and g = 6.67 x 10^-11 nm^2/kg^2. (round your answer to three significant digits.)

We have that from the Question it can be said that  the gravitational force is given as

F=12.864N

From the Question we are told

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 m1*m2/r^2

Use Newton's Law of Gravitation to compute the work W required to propel a 800 kg satellite out of the earth's gravitational field. You may assume that the earth's mass is 5.98 x 10^24 kg and is concentrated at its center. Take the radius of the earth to be 6.37 x 10^6 m and G = 6.67 x 10^-11 Nm^2/kg^2. (Round your answer to three significant digits.)

Generally the equation for Gravitational Force is mathematically given as

F=12.864N

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
