Challenge Problems
Push your limits with challenges.
Question 1
A satellite is orbiting Earth at an altitude where the gravitational pull is only half of what it is at Earth’s surface. What is its escape speed compared to that from the surface?
💡 Hint: What happens to the escape speed when gravity is halved?
Question 2
Determine how the escape speed changes if the radius of Jupiter is doubled and its mass remains unchanged.
💡 Hint: Remember the inverse relationship between radius and escape speed.
