The centripetal acceleration of the space shuttle is (0.9g)
Explanation:
The period of revolution of the space shuttle is
From the period, we can calculate the angular speed of the space shuttle, which is given by
Now we can calculate the centripetal acceleration of the space shuttle, given by
where
is the angular speed
is the distance of the shuttle from the Earth's centre (it is the sum of the Earth's radius, 6400 km, and of the altitude of the space shuttle, 300 km)
Substituting and solving, we find
And since , this can be rewritten as
