Question 1
What is the formula for calculating escape velocity?
- v = β(GM/r)
- v_esc = β(2GM/r)
- v = GM/r^2
π‘ Hint: Look for the formula that includes a square root and double G.
Question 2
True or False: A Hohmann transfer orbit is a method to move from a higher orbit to a lower one only.
- True
- False
π‘ Hint: Think about what a transfer orbit does.

Challenge Problems
Push your limits with challenges.
Question 1
A satellite needs to transport from a low Earth orbit (radius = 7,000 km) to a geostationary orbit (radius = 42,164 km). Calculate the required Ξv for the Hohmann transfer.
π‘ Hint: Use the formula: v = β(GM/r) for velocity.
Question 2
Calculate how much energy is required to launch a satellite of 1000 kg to escape velocity on Earth. Use v_esc = β(2GM/r).
π‘ Hint: Don't forget to calculate the escape velocity using G, M, and r first.
