At a certain distance from the center of a planet the acceleration due to the gravitational attraction of that planet is 4 m/s?. What is the acceleration at twice that distance? 8m/s^2 2m/s^2 1m /s^2 3m/ s^2 A satellite revolves around a planet along an elliptical orbit. The minimum and the maximum distances between the planet and the satellite are related as 3:4. The speed of the satellite at the point where it is closest to the planet is 12 km/s. What is its speed when it is at the most distant point on its orbit? I guess 9km/s? Please explain the answer of these questions why it is correct though
