satellite is in circular orbit around the Earth at an altitude of 3.74 x 10^6 m (a) Find the period of the orbit. (Hint: Modify Kepler's third law so it is suitable for objects orbiting the Earth rather than the Sun. The radius of the Earth is 6.38 x 10^6 m, and the mass of the Earth is 5.98 x 10^24 kg.) (b) Find the speed of the satellite. km/s (c) Find the acceleration of the satellite m/s^2 toward the center of the earth
