l. The National Academy of Science1 in order to gather information on deforestation, wishes to place a S kg satellite in a polar orbit around the earth. The radius of the earth is approximately 6.38 x [03 km, and the acceleration of' gravity at the orbital altitude of ll] km is veryr nearly the same as it is at the surface of the earth. a. Construct a force diagram for the satellite described in the statement above. b. Explain what is causing the centripetal force for the satellite. c. Calculate how long it would take for the satellite to make one complete revolution around the earth. 2. The earth's orbit around the sun is very nearlyr circular1 with an average radius of 1.5 x It]H km. Assume the mass of the earth is ti 3: ll]24 kg. a. Calculate the average speed of the earth in its orbit around the sun. b. Calculate the magnitude of the earth's average acceleration in its orbit around the sun. c. Use your answer in (b) to calculate the force of the Sun on the Earth
