2. A geosynchronous communications satellite in stationary orbit is used to relay radio messages from one point to another around the earth's curved surface. Re=6.38x10^6 m, me=5.97×10^24 kg, and G=6.674×10^-11 Nm^2/ kg^2 3. An earth satellite moves in a circular orbit with an orbital speed of 5000 m/s. Find the radial accelerates of the satellite in its orbit given me=5.97×10^24 kg and G=6.674×10^-11 Nm^2/kg^2

4. A planet has been detected in a circular orbit around the star Rho1 Cancri with an orbital radius equal to 1.65×10^10m. The orbital period of this planet is approximately 14.5 days. Which is the approximate mass of the star Rho1 Cancri?

5. What is the period of the revolution of a satellite with mass m that orbits the earth in a circular path or radius 7880 km (about 1500 km above the earth's surface)? G=6.674×10^-11 Nm^2 /kg^2 and Me=5.97 x 10^24 kg.

6. Calculate the speed with which you would have thrown a rock to put it into orbit around the asteroid 234 Ida near its surface assuming, 234 ida is spherical. Ida's mass is 4×10^16 kg and its radius is 16km

8. in order to be available all the time a communications satellite must orbit in a circle above the equator and must remain above thenssme pont on the earths surface. how long does it take for a communications satellite to make one complete orbit around th earth? Re=6.38×10^6 m, me=5.97×10^24 and G- 6.674 × 10^-11 Nm^2/kg2
