Q. An oscillator with a mass of 430 g and a period of 0.900 s has an amplitude that decreases by 1.00% during each complete oscillation. If the initial amplitude is 9.20 cm, what will be the amplitude after 44.0 oscillations? At what time will the energy be reduced to 36.0% of its initial value?

Q. An ice skater performs a pirouette (a fast spin) by pulling in his outstretched arms close to his body. What happens to his moment of inertia about the axis of rotation?
