1. Show the derivation of the formula for acceleration of a satellite. Make sure you explain how Newton's Laws are combined.
2. The Earth has a mass of 6.0 x 107 kg, and the Sun has a mass of 20x 103 kg. The Earth orbits the Sun at an average distance of 1.5x 10 km. The gravitational constant is 6.67 x 10" Nm²/kg? What is the force of gravity of the Sun on the Earth? What is the force of gravity of the Earth on the Sun?
3. If the mass of your body is 70 kg, then what is your weight? Acceleration due to gravity is 9.8m/s. You can also calculate the gravitational force on your body using the formula which has the gravitational constant. For this you will need the radius of the Earth which is 6400 km. The other information you need is in the prior problem. Compare the two gravitational forces that you have calculated.
4. What is the acceleration due to gravity experienced by a satellite with a mass of 4500 kg. The satellite is in orbit 140 km. above the Earth. The mass of the Earth is 6.0 x107 kg, and has a radius of 6400 km. The gravitational constant is listed in #2 Formulas: Fe= mg F = Gm, m2/r ai - Gm2/ r
