Challenge Problems
Push your limits with challenges.
Question 1
A satellite needs to transfer from a low Earth orbit to a geostationary orbit. Calculate the required change in velocity if the low Earth orbit is 300 km above the Earth's surface and the geostationary orbit is 36,000 km above the surface.
💡 Hint: Remember to apply the escape velocity formula and differences in kinetic energy.
Question 2
Design a fuel-efficient plan for a mission to place a satellite into a polar orbit. Discuss the key factors that need to be considered.
💡 Hint: Reflect on the orbital dynamics and the physics behind satellite placement.
