Answer:
4557.88 m/s
Explanation:
M = mass of earth = 5.98 x 10²⁴ kg
R = radius of earth = 6.4 x 10⁶ m
r = orbital radius of satellite = 3R = 3 x 6.4 x 10⁶ = 19.2 x 10⁶ m
[tex]v[/tex] = speed of the satellite
speed of the satellite is given as
[tex]v=\sqrt{\frac{GM}{r}}[/tex]
[tex]v=\sqrt{\frac{(6.67\times 10^{-11})(5.98\times 10^{24})}{19.2\times 10^{6}}}[/tex]
[tex]v[/tex] = 4557.88 m/s
