The diagram represents a 4.0 x 10^2-kilogram satellite, S, in a circular orbit at an altitude of 5.0 x 10^3 meters. The orbital speeds of the satellite is 6.0 x 10^3 meters per second and the radius of the Earth, R, is 6.4 x 10^6 meters. The centripetal acceleration of the satellite shown is closest to:

• 9.8 m/s^2

• 4.9 m/s^2

• 3.2 m/s^2

• 1.6 m/s^2

If the altitude of the satellite decreased, its centripetal acceleration would:

• decrease

• increase

• remain the same

The diagram shown represents a 4.0 x 10^2-kilogram satellite, S, in a circular orbit at an altitude of 5.6 x 10^3 meters. The orbital speed of the satellite is 5.7 x 10^3 meters per second and the radius of the Earth, R, is 6.4 x 10^6 meters. The centripetal acceleration of the satellite is approximately:

• 9.8 m/s^2

• 4.9 m/s^2

• 2.7 m/s^2

• 1.4 m/s^2

If the altitude of the satellite decreased, its centripetal acceleration would:

• decrease

• increase

• remain the same

The diagram shows an object with a mass of 1.0 kilogram attached to a string 0.50 meter long. The object is moving at a constant speed of 5.0 meters per second in a horizontal circular path with center at point O. While the object is undergoing uniform circular motion, its acceleration:

• has a magnitude of zero

• increase in magnitude

• is directed toward the center of the circle

• is directed away from the center of the circle
