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 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? J

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...
