A satellite is in circular orbit around the earth at an altitude of 2.80 x 10^6 m. Find (a) the period of the orbit, (b) the speed of the satellite, and (c) the acceleration of the satellite.
A)
Distance, d = 6371000 + 2800000 = 9.17 x 10^6 m
From Kepler’s law,
T^2 = [(4 pi^2/(6.67 x 10^-11 x 5.98 x 10^24)](9.17 x 10^6)^3
T = 8737.58 sec = 2.43 hrs
B)
V^2 = (6.67 x 10^-11 x 5.98 x 10^24)/(9.17 x 10^6)
V = 6595.21 m/s = 6.60 km/s
C)
Acceleration, a = v^2/r = 6595.21^2/9.17 x 10^6 = 4.74 m/^2
Comment in case any doubt please rate my answer .....

6. [2pt] A satellite is in a circular orbit around the Earth. The period of the satellite is 20.9 hr. Calculate the radius of the satellite's orbit. Data: My = 5.98 x 10kg, -6.67 x 10 Nm²/kg? Answer: Not yet correct, tries 1/20 S t Al Answers Last Answer: 4.8x10^21 m Hint: Uniform circular motion means that the satellite is accelerated towards the center. The acceleration can be obtained from the law of gravity and the second law combined.

A satellite is launched to orbit the Earth at an altitude of 3.45 x 10^7 m for use in the Global Positioning System (GPS). Take the mass of the Earth to be 5.97 x 10^24 kg and its radius 6.38 x 10^6 m. What is the orbital period of this GPS satellite? With what speed does it orbit the Earth?
Consider a satellite of mass m moving in a circular orbit around the Earth at a constant speed v and at an altitude h above the Earth's surface as illustrated in the figure. (a) Determine the speed of the satellite in terms of G, h, Re (the radius of the Earth), and Me (the mass of the Earth). (b) If the satellite is to be geosynchronous (that is, appearing to remain over a fixed position on the Earth), how fast...
