Question

Calculate the speed of a satellite moving in a stable circular orbit about the Earth at a height of 4930 km .

Answer 1

The speed of the satellite moving in a stable circular orbit about the Earth is 5,916.36 m/s.

Speed of the satellite

v = √GM/r

where;

• M is mass of Earth
• G is universal gravitation constant
• r is distance from center of Earth = Radius of earth + 4930 km

v = √[(6.626 x 10⁻¹¹ x 5.97 x 10²⁴) / ((6371 + 4930) x 10³)]

v = 5,916.36 m/s

Thus, the speed of the satellite moving in a stable circular orbit about the Earth is 5,916.36 m/s.
