13.23. Two satellites are in circular orbits around a planet that has radius 9.00 X 10°m. One satellite has mass 68.0 kg, orbital radius 7.00 X 107m, and orbital speed 4800 m/s. The second sat- ellite has mass 84.0 kg and orbital radius 3.00 X 10'm. What is the orbital speed of this second satellite?

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 complete one circular orbit around a space station in the same amount of time. Each satellite has mass m and radius of orbit L. The satellites fire rockets that provide the force needed to maintain a circular orbit around the space station. The gravitational force is negligible.
Rank the net force acting on each satellite from their rockets.
Rank from largest to smallest. To rank items as equivalent, overlap them
A) m=200 kg and L= 5000m
B) m=400 kg and L=2500m
C)m=100kg and L=2500m
D)m=100kg and L=10000m
E)m=800kg and L=5000m
