Challenge Problems
Push your limits with challenges.
Question 1
A satellite is launched from the Earth. If the mass of the Earth is approximately 5.97 × 10^24 kg, calculate its escape velocity. Assume the radius of the Earth is 6.371 × 10^6 m.
💡 Hint: Remember to substitute the values into the escape velocity formula.
Question 2
Discuss how the escape velocities of gaseous planets compare to rocky planets, providing a reasoning based on their sizes and gravitational differences.
💡 Hint: Consider how size affects gravitational pull.
