A satellite is in a circular orbit around the earth. The period of the satellite is 22 hour.
1. Obtain the radius of the orbit of the satellite. Data: Mass of the earth = 5.98 times 1024 kilogram. 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.
2. Determine what is the speed of the satellite?
