A communications satellite is in a synchronous orbit that is
3.09×107m directly above the equator. The satellite is located
midway between Quito, Equador, and Belem, Brazil, two cities almost
on the equator that are separated by a distance of 3.48×106m.
Calculate the time it takes for a telephone call to go by way of
satellite between these cities. Ignore the curvature of the
earth.

An artificial satellite is in a circular orbit d=470.0 km above
the surface of a planet of radius r=3.95×10^3 km. The
period of revolution of the satellite around the planet is T=1.15
hours. What is the average density of the planet?

The
largest satellite of the dwarf planet Pluto is Charon which has a
mass of 1.586x 10^22 kg and a 1212 km diameter. Charon is being
visited by the intrepid geologist astronaut, Lil Suzi. Glad that
her long trip from Ceres is over, in celebration she pitched a 3 kg
piece of Charon’s ice horizontally at 22 meters per second over the
edge of serendipity chasma (a canyon) at a location where the
canyon is 1560 meters deep.

A satellite of mass 100 kg is in circular orbit about planet
Uzaz, which has a mass M and radius R, at an altitude (above the
surface) h.
(a) (2 points) Express the linear speed v of
the satellite in terms of the given variables and the universal
gravitational constant.
(b) (3 points) Suppose that if h = 1 × 104 km,
the period of the orbit is T = 11 hours. If Uzaz has a mass of 7.0

A geosynchronous orbit is one in which the satellite orbits
above the equator and has an orbital period of 24 hours so that it
is always above the same point on the spinning earth. Calculate the
altitude of such a satellite.
(b) What is the gravitational field experienced by the
satellite? Give your answer as a percentage in relation to the
gravitational eld at the earth's surface.
Instruction:
First, solve the problem in terms of variables. Then,
calculate the numerical...
A geostationary satellite is 42000km above the center of earth.
If the satellite latitude is 50o north with respect to the earth
station and the spherical earth mean radius is 6371 km. Calculate
the satellite elevation angle.
