A satellite is orbiting around a planet in a circular orbit. The radius of the orbit, measured from the center of the planet is R=1.9 x 107 m.  The mass of the planet is M = 4.4 x 1024 kg. 

Part (a) Express the magnitude of the gravitational force F in terms of M, R, the gravitational constant G, and the mass m of the satellite.

Part (b) Express the magnitude of the centripetal acceleration a, of the satellite in terms of the speed of the satellite v, and R. 

Part (c) Express the speed v in terms of G, M and R. 

Part (d) Calculate the numerical value of v, in m/s.

Six artificial satellites circle a space station at constant speed. The mass m of each satellite, distance L from the space station, and the speed v of each satellite are listed below. The satellites fire rockets that provide the force needed to maintain a circular orbit around the space station. The gravitational force is negligible.

1. m = 200 kg, L = 5000 m, v = 120 m/s

2. m = 800 kg, L = 10,000 m, v = 40m/s

3. m=400 kg, L = 2500 m, v = 80m/s 

4. m = 100 kg, L = 2500 m, v = 160m/s

5. m = 300kg, L = 10,000 m, v = 80 m/s

6. m = 200 kg, L = 5000 m, v = 160 m/s

Part A Rank each satellite from largest to smallest based on its period.

Part B Rank each satellite from largest to smallest based on its acceleration.

A 7500-kg satellite has an elliptical orbit, as in the figure. Thepoint on the orbit that is farthest from the earth is called theapogee and is at the far right side of the drawing. The point onthe orbit that is closest to the earth is called the perigee and isat the far left side of the drawing. Suppose that the speed of thesatellite is 2970 m/s at the apogee and 8300 m/s at theperigee.

(a) Find the work done by the gravitational force when thesatellite moves from the apogee to the perigee.

(b) Find the work done by the gravitational force when thesatellite moves from the perigee to the apogee.
