Problem 6 A figure skater enters into a spin with arms outstretched. This body position gives them a moment of inertia of 2.4 kg m². They're initially spinning through 1.2 revolutions per second. Then, with no external torques acting on them, they pull their arms in close to their body, reducing their moment of inertia to 0.4 kg m². What is their angular velocity after they pull their arms in? Don't forget units! cad
