14. A satellite is in Earth orbit with an altitude at perigee of 1000 km and an altitude at apogee of 2000 km.(Note it says altitude not radius).

What is thesemimajoraxis of the orbit?

Please express your answer in kilometers and just enter the numeric portion of you answer in the box provided (don't include units).

17. For a satellite in the same orbit as above (in Earth orbit with an altitude at perigee of 1000 km and an altitude at apogee of 2000 km),If the true anomaly is 290, is the flight-path angle positive or negative?

Why?

18. A spacecraft is in a circular orbit around Earth with a radius of 10,000 km. Determine the spacecraft's velocity in this circular orbit.

Please only submit a number for your answer. I will assume it is in km/sec

19. Can a satellite"hang"directly over Denver?(Yes or No)

Why or why not?

20.

• What type of ground track does a geostationary spacecraft have?
• How about a geosynchronous spacecraft with a 30 inclination and zero eccentricity?
