Question a. A 2300-kg satellite is orbiting the earth at an altitude equal to twice the earth's radius.
(i) Find the satellite's weight at that altitude.
(ii) Find the gravitational force exerted by the earth on the satellite at that altitude.
Question b.
(i) What is the local g value at an earth altitude of 250 km (about where the Space Shuttle often orbits)?
(ii) What is the speed of the Space Shuttle's orbit at an altitude of 250 km?
(ii) At what earth altitude is the local g value 90% of earth's surface g value?
(iv) What is the speed of a satellite orbiting earth where local g is 10% of earth's surface g?
Question c. A certain planet (not Earth) has a radius of 5.59 x 10^6 m. A satellite that orbits this planet at an altitude of 490 km will complete a revolution every 170 minutes. What is the value of g on the surface of this planet?
