From the question,
Using Impulse, the product of the constant force, F and time t equals the product of the mass of the body and change in velocity.
This implies that
You can also use the equation of linear motion,
But

Explanation:
The magnitude of the centripetal acceleration can be related to the angular velocity and radius as:
(1)
Solving for w:
(2)
Replacing a=9,8m/s2 and r=6,375,000m:
(3)
And the angular velocity relates to the linear velocity:
The perimeter of the orbit is:
