A 1 036-kg satellite orbits the Earth at a constant altitude of 110-km. (a) How much energy must be added to the system to move the satellite into a circular orbit with altitude 194 km? MJ? (b) What is the change in the system's kinetic energy? MJ? (c) What is the change in the system's potential energy? MJ?
Solutions
Expert Solution
Mass of the satellite m=1036 kg
Altitude of the satellite 
Total energy of the satellite in a orbit of radius r, from
thecenter of the Earth is
Hence energy of the satellite at 
And the energy of the satellite at 
is
Hence energy needed to be added to the system to move the
satellitefrom
to 
is

(a) A 374 kg satellite orbits the Earth at a height of 3197 km
above the Earth's surface. Assume the Earth has a mass of 5.98 x
1024 kg and a radius of 6,380 km. Find the velocity (in
m/s) of the satellite in its orbit.
(b) Calculate the period of the satellite's orbit when it orbits
the Earth at a height of 3197 km above the Earth's surface. State
your answer in minutes.

1) An
Earth satellite is in a circular orbit at an altitude of 500 km.
Explain why the work done by the gravitational force acting on the
satellite is zero. Using the work-energy theorem, what can you say
about the speed of the satellite?

A 425 kg satellite is in a circular orbit at an altitude of 400
km above the Earth's surface. Because of air friction, the
satellite eventually falls to the Earth's surface, where it hits
the ground with a speed of 2.00 km/s. How much energy was
transformed to internal energy by means of friction?

A geostationary satellite orbits the Earth in 24h, so that it
appears to be at a fixed position above an observer on Earth. Find
its distance from Earth and its velocity by equating the
gravitational pull on the satellite to its centrifugal force
(GME=4 x1014 m3 /sec2
). A precise atomic clock is present on that satellite. Use special
relativity to estimate the time difference after a year between
this clock and a similar one on Earth. Which clock is...
