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.

Generally the equation for Gravitational Force is mathematically given as

F=12.864N

The work done in propelling the satellite is 5 x 10¹⁰ J.

The given parameters;

The work done in propelling the satellite is calculated as follows;

where;

Substitute the given parameters and solve for the work done;

Thus, the work done in propelling the satellite is 5 x 10¹⁰ J.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
