20. Imagine a satellite in a circular orbit around the earth, passing precisely over the geographic poles. Suppose the radius of the orbit is 1 x 104 km. Imagine a plane P that contains the equator and extends indefinitely into space. Assuming the acceleration due to gravity exerted on the satellite is 9.8 m/sz , how long does it take the satellite to pass from plane P to a point directly over point Q as it travels northward? A. 3000 s B. 3600 s C. 3345 s D. 4500 s
