    Find the height H of a geosynchronous satellite above the surface of the earth. You may well want to find the radius of the orbit R first. You may use the following constants: The universal gravitational constant G is 6.67×10−11Nm2/kg2. The mass of the earth is 5.98×1024kg. The mass of the satellite is 2.10×102kg. The radius of the earth is 6.38×106m. Give the height of the orbit above the surface in km to three significant digits.

    Consider a 435 satellite in a circular orbit at a distance of 3.19X10^4 above the Earth’s surface. What is the minimum amount of work W the satellite’s thrusters must do to raise the satellite to a geosynchronous orbit? Geosynchronous orbits occur at approximately 3.6X10^4 above the Earth’s surface. The radius of the Earth and the mass of the Earth are RE=6.37X10^3 and 5.97X10^24 respectively. The gravitational constant is G = 6.67X10^-11 Assume the change in mass of the satellite is...
