Question:
1. What would be the weight of a 78-kg astronaut on a planet 10 times as massive as Earth and having 4 times the Earth's radius
2. The mass of Jupiter is 1.9 1027kg and its radius, R, is 7.15 107 m. What is the value of g at a height of 4.0R above the surface of Jupiter?
3. The period of a moon orbiting Saturn is 110 days. What would the new period in days be if the moon became 2 times more massive and the orbital radius of the moon became 3 times the original value.
4. GPS (Global Positioning System) satellites orbit at an altitude of 4.51x107 m above Earth. Find the orbital speed of such a satellite. The mass of the Earth is 5.98x1024 kg, and the radius of the Earth is approximately 6.38x106 m.
5. Two different satellites, satellite A with a mass of 4m and satellite B with a mass of 7m, orbit around a massive planet which has mass M. The orbital radius of satellite A is (1/2)R and the orbital radius of satellite B is 2R. What is the ratio of the gravitational acceleration, aA/aB
