An Earth satellite is in a circular orbit at an altitude of 500
km. Explain why the work done by the gravitational force acting on
the satellite is zero. Using the work-energy theorem, what can you
say about the speed of the satellite?

A 400 kg satellite is in a circular orbit at an altitude of 525 km
above the Earth's surface. Because of air friction, the satellite
eventually falls to the Earth's surface, where it hits the ground
with a speed of 2.30 km/s. How much energy was transformed into
internal energy by means of air friction?

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...

Two identical earth satellites, A and B, are to be launched into
circular orbits about Earth's center. Satellite A is to orbit at an
