3. An ice skater can increase their angular velocity during a spin by pulling their arms inward, lowering their moment of inertia. The only external torques are small forces at small radii (in particular, friction in the tip of their skate), and can be ignored. Suppose they begin with their arms fully extended and bring them fully in, reducing their moment of inertia by half. (a) By what factor will their angular velocity ω change? Explain. (b) By what factor...
