Question

The International Space Station, ISS hereafter, has an orbital period of approxi- mately 93 minutes. Determine the following: 12. How fast is the ISS moving? 13. How far above the surface of the Earth is the ISS? 14. Using only your answer to question 12 and the given orbital perdiod of the ISS, determine how high the Hubble Space Telescope orbits above the surface of the Earth, if its orbital period is 95.42 minutes 15. If NASA launched portable rocket-boosters to the ISS in order to increase its height above the surface of the Earth by 1.1 × 106 m. How much work would need to be done by the rocket-boosters? 16. What would be the new orbital period of the ISS? 17. What orbital speed corresponds to the period from the previous question?

Answer 1

In this question , period of time period is used and Vis-Viva equation has been used.

So 14 ms ms
since mass of the satellite is not given so work done per unit of mass is found out.

Please rate it positively.
