The National Academy of Science, in order to gather information on deforestation, wishes to place a 500. kg infrared-sensing satellite in a polar orbit around the earth. The radius of the earth is approximately 6.38 x 10^3 km, and the acceleration of gravity at the orbital altitude of 160 km is very nearly the same as it is at the surface of the earth.
the centripetal force on the satellite, by what?
Determine how long it would take for the satellite to make one complete revolution around the earth.
