(a) Suppose you are at the earth’s equator and observe a satellite passing directly overhead and moving from west to cast in the sky. Exactly 12.0 hours later, you again observe this satellite to be directly overhead. How far above the earth’s surface is the satellite’s orbit? (b) You observe another satellite directly overhead and traveling east to west. This satellite is again overhead in 12.0 hours. How far is this satellite’s orbit above the surface of the earth?

A 1.07 kg mass is at the center of a uniform spherical shell of mass 1.06 * 10 ^ 20 * kg and radius 1.02 * 10 ^ 6 * m Find the resultant gravitational force on the mass? Also find the resultant gravitational force of the mass if it is placed just outside the shell? Magnitude? Direction? Find the value of g just outside the shell?
For a satellite to be in a circular orbit 890 km above the surface of the earth, (a) what orbital speed must it be given, and (b) what is the period of the orbit (in hours)?
You are designing a communications satellite to be placed in circular orbit around theEarth with a period of 8.00 hours. Recall that the mass and the radius of the Earth areME = 5.97 × 1024 kg and RE = 6.37 × 106 m.(a) At what height above the surface of the Earth should the satellite be placed?Give your answer in units of kilometers (km).(b) What is the orbital speed of this satellite, in km/s?
