3. A spacecraft in an elliptical, polar orbit, with a semimajor axis of6,778 km and an eccentricity of 0.04, is at perigee as it passes theascending node. How long will the spacecraft take to reach theNorth Pole?
5/54. For a spacecraft in a circular, polar orbit with an altitude of 400km, find the spacecraft’s location, argument of latitude, u, in 40minutes if the spacecraft is at the ascending node.

A spacecraft in an elliptical, polar orbit, with a semimajor axis of6,778 km and an eccentricity of 0.04, is at perigee as it passes theascending node. Find the true anomaly 40 minutes later.Correct 5/5
9. How long will a spacecraft in an elliptical orbit with a apogeealtitude of 650 km take to decay to an altitude of 160 km, if theaverage apogee decay rate is 0.6 km/day?
10. A spacecraft is in a circular orbit at an altitude of 200 km and aninclination of 28°. How far will the ascending node move in one day?In which direction will it move?
