A satellite orbits the Earth uniformly in a circular orbit with a velocity of magnitude 4.00 km/s. Use Newton's gravitation force as the force in Newton's Law of Acceleration, using also the centripetal acceleration . Solve for radius r of the satellite's orbit in terms of v . (a) Find then the altitude of the satellite above the surface of the Earth. Earth's mass and radius are 5.9810 kg and 6.3810 km. (b) Find the time it takes the satellite to orbit one time by using the circumference of the orbit and the velocity.
