Answer:
(a). The orbital speed of this space station is 7906.42 m/s.
(b). The period of the space station is 5062.2 sec.
Explanation:
Given that,
Gravitational constant [tex]G=6.67\times10^{-11}\ Nm^2/kg^2[/tex]
Mass of earth [tex]M_{e}=5.97\times10^{24}\ kg[/tex]
Radius of earth [tex]R_{e}=6.37\times10^{3}\ km[/tex]
(a). We need to calculate the orbital speed of this space station
Using formula of orbital speed
[tex]v=\sqrt{\dfrac{GM}{r}}[/tex]
[tex]v=\sqrt{\dfrac{6.67\times10^{-11}\times5.97\times10^{24}}{6.37\times10^{6}}}[/tex]
[tex]v=7906.42\ m/s[/tex]
(b). We need to calculate the period of the space station
Using formula of period
[tex]T=\dfrac{2\pi r}{v}[/tex]
Put the value into the formula
[tex]T=\dfrac{2\pi\times6.37\times10^{6}}{7906.42}[/tex]
[tex]T=5062.2\ sec[/tex]
Hence, (a). The orbital speed of this space station is 7906.42 m/s.
(b). The period of the space station is 5062.2 sec.
