Use the result of Exercise 35 to calculate the work required to place a 2000-kg satellite in
Question:
Use the result of Exercise 35 to calculate the work required to place a 2000-kg satellite in an orbit 1200 km above the surface of the earth. Assume that the earth is a sphere of radius Re = 6.37 × 106 m and mass Me = 5.98 × 1024 kg. Treat the satellite as a point mass.
Data From Exercise 35
The gravitational force between two objects of mass m and M, separated by a distance r, has magnitude GMm/r2, where G = 6.67 × 10−11 m3kg−1s−1.
Show that if two objects of mass M and m are separated by a distance r1, then the work required to increase the aseparation to a distance r2 is equal to W = GMm(r1−1 − r2−1).
