A figure skater can increase her spin rotation rate from an initial rate of 1.0rev every 1.5s to a final rate of 2.5rev/s. If her initial moment of inertia was 4.6kg.m^2, what is her final moment of inertia? How does she physically accomplish this chage? 문제풀이 영상입니다.

'We Learn to Share' was founded by a 10th grader in South Korea named Elena (Korean name: Seungeun Lee) in 2021 because she realized a love for sharing what she had learned in school. Starting from 2022, 'We Learn to Share' has become the first and only international high school student-led organization in the entire world dedicated to educational volunteer activities. Elena has invited highschool students from different countries and schools all over the world (+ 13 schools from +4 countries) to this channel. Just watch and learn!
