  1. Application of Rotation Homework and Review Questions

  2. Earth Constants Mass of Earth- 5.98 X 1024 kg mean radius of Earth- 6.378 x 106 m

  3. A 600 kg satellite moves in a circular orbit around the Earth at a height equal to 1 mean radius of the Earth above the surface of the planet. Find the • Satellite’s orbital speed • Satellite’s period of revolution • Gravitational force acting on satellite • Acceleration due to gravity on satellite • Frequency of the satellite

  4. A satellite moves in a circular orbit around the Earth at 5000 m/s. Determine the • Satellite’s distance from the center of the Earth • Satellite’s distance from the surface of the Earth • The period of the Satellite’s orbit

  5. A 345 kg satellite is orbiting the earth 550 km above the surface of the planet (radius and mass in previous question). Find the following • Orbital speed • Orbital radius • What is the centripetal force on the satellite? • What force keeps the satellite in circular orbit around the earth?

  9. Question #1 • Apollo II orbit around the moon was 111 km above the surface. The radius of the moon is 1785 km and the mass of the moon is 7.3 x 10 22 kg. • How many minutes did it take to orbit the moon once? • At what velocity did it orbit the moon

  10. Question #2 • Mimas, a moon of Saturn, has a orbital radiusof 1.87 x 10 8 m and an orbital period of 23 hours. • Find the mass of Saturn

  11. A satellite orbits Neptune 4000 km above its surface. Given that the mass of Neptune is kg and the radius of Neptune is m, calculate the orbital speed of the satellite.
