| A 2100 kg satellite is to be placed into a circular, geostationary orbit above the equator. |
| (A) |
How high above the equator will the satellite have to orbit in order for it to be stationary above one location on the equator ? |
| (B) |
How fast will the satellite be moving in this orbit ? |
| (C) |
What is the minimum energy required to place the satellite into orbit ? |
| (D) |
Suppose the satellite was launched vertically with an initial speed that would just allow it to reach a maximum altitude equal to that of the geostationary satellite. Determine the initial launch speed, assuming it was launched vertically from the ground at the equator |
