Answer:
The acceleration of the satellite is
Explanation:
The acceleration in a circular motion is defined as:
(1)
Where a is the centripetal acceleration, v the velocity and r is the radius.
The equation of the orbital velocity is defined as
(2)
Where r is the radius and T is the period
For this particular case, the radius will be the sum of the high of the satellite () and the Earth radius (
) :
Then, equation 2 can be used:
⇒
Finally equation 1 can be used:
Hence, the acceleration of the satellite is
