Question

Kepler’s Laws of Planetary Motion:

1. A satellite is placed into geosynchronous orbit around the Earth (That means that it orbits once per day and thus stays above the same location over the Earth). Compute the distance from the Earth that the satellite is at.

Kepler’s Laws of Planetary Motion:
1. A newly discovered exoplanetary system has a planet orbiting
its host star at 50 times the distance from the Earth to the sun.
If the orbital period of the planet is 40 Earth years, what is the
mass of the host star?
2. The mass of the Earth is approximately 6 × 1026
kg. If the moon takes 27 days to orbit the Earth, how far is the
moon from the Earth?
3. A...

A 390.45 kg satellite is geosynchronous orbit around the Earth
stays over the same spot and takes 24 hours to make one
revolution. Given the following data, determine the
satellite

You want to put a satellite in a geosynchronous orbit around the
earth. (This means the asteroid takes 1 day to complete a turn
around the earth.)
(a) At what height above the surface do you need to put it?
(b) How fast is it moving?
(c) How does the answer to (b) compare to the escape speed from the
earth, for an object at this height?

(Satellite Simulation)
Theory: State Kepler’s laws of planetary motion (all three).
Include the diagrams and formula as well.

Consider a satellite of mass m in a circular orbit of radius r
around the Earth of mass ME and radius RE.
1.
What is the gravitational force (magnitude and direction) on
the satellite from Earth?
2.
If we define g(r) to be the force of gravity on a mass m at a
radial distance r from the center of the Earth, divided by the mass
m, then evaluate the ratio g(r)/g(RE)to see how g varies with
radial distance. If...

Two satellites are in circular orbits around the earth. The
orbit for satellite A is at a height of 406 km above the earth's
surface, while that for satellite B is at a height of 904 km. Find
the orbital speed for satellite A and satellite B.

Two satellites are in circular orbits around the earth. The
orbit for satellite A is at a height of 556 km above the earth’s
surface, while that for satellite B is at a height of 888 km. Find
the orbital speed for (a) satellite A and
(b) satellite B.

You wish to put a satellite in orbit around Earth.
Part A
Which takes more energy per kilogram of satellite: launching the
satellite from the ground to a height of 1600 km above the ground
or placing the satellite into orbit once it has reached that
altitude?
-Both energies are nearly the same.
- More energy is required to get the satellite up to the
appropriate height than is required to put the satellite into orbit
once it is already...

A satellite of mass 3.00 x 104 kg is placed in orbit
5.00 x 105 m above the surface of Jupiter. Please refer
to the data table for planetary motion included in this lesson.
Determine the force of gravitational attraction between the
satellite and Jupiter.
What must be the orbital speed of the satellite?
What must be the value of the gravitational field constant, g,
at the location of the satellite?
One of the moons of Jupiter is Europa. It's...

A satellite is put into an elliptical orbit around the Earth.
When the satellite is at its perigee, its nearest point to the
Earth, its height above the ground is ℎp=241.0 km,hp=241.0 km, and
it is moving with a speed of ?p=7.850 km/s.vp=7.850 km/s. The
gravitational constant ?G equals 6.67×10−11 m3·kg−1·s−26.67×10−11
m3·kg−1·s−2 and the mass of Earth equals 5.972×1024 kg.5.972×1024
kg.
When the satellite reaches its apogee, at its farthest point
from the Earth, what is its height ℎaha above...
