Satellite orbits the earth at a distance equal to twice the earth's radius above the surface of the earth (the total distance from the center of the earth is three times the radius of the earth).
3) The satellite has a mass of 60 kg. What is the force of attraction between the earth and the satellite? 588 N 318 N 65.3 N 21.0 N 7.26 N 4) What is the centripetal acceleration of the satellite? 88.2 m/s2 29.4 m/s2 9.80 m/s2 3.27 m/s2 1.09 m/s2 5) With what speed must the satellite move to follow a circular orbit? 4565 m/s 1987 m/s 567 m/s 222 m/s 18 m/s 6) If the mass of the satellite was increased, what would need to happen to the speed to keep the same radius of orbit? increase decrease remain the same
