The Guardians of the Universe launch a satel- lite that goes into orbit at a distance of 16287 km from the center of the earth. If the orbit is circular what is its speed? The universal gravitational constant is 6.67 x 10-11 N. m/kg and the mass of the earth is 5.98 x 1024 kg. Answer in units of m/s. 040 (part 1 of 2) 10.0 points The planet Mars requires 1.84 years to orbit the sun, which has a mass of 1.989 x 1030 kg, in an almost circular trajectory. Find the radius of the orbit of Mars as it circles the sun. The gravitational constant is 6.672 10-11 N m/kg. Answer in units of m. 041 (part 2 of 2) 10.0 points. Find the orbital speed of Mars as it circles the sun. Answer in units of m/s. 042 (part 1 of 2) 10.0 points Two satellites A and B orbit the Earth in the same plane. Their masses are m and 6m, respectively, and their radii r and 3r, respectively.
