What is the angular speed of a satellite in a geo-synchronous orbit around the Earth?
|
7.3 × 10-5 rad s-1
|
|
2.6 × 10-1 rad s-1
|
|
24 rad s-1
|
|
5.0 × 106 rad s-1
|
Explanation:
Detailed explanation-1: -For a geostationary satellite the angular speed in units of radians per hour is: /12.
Detailed explanation-2: -For example, a geostationary satellite completes one orbit per day above the equator, or 360 degrees per 24 hours, and has angular velocity = (360°)/(24 h) = 15°/h, or (2 rad)/(24 h) ≈ 0.26 rad/h.
Detailed explanation-3: -Geostationary orbit (GEO) In order to perfectly match Earth’s rotation, the speed of GEO satellites should be about 3 km per second at an altitude of 35 786 km.
Detailed explanation-4: -We know that angular speed is given by the formula, = /t.
