An oscillator with a mass of 430 g and a period of 1.20 s has an amplitude that decreases by 1.00% during each complete oscillation.
a.) If the initial amplitude is 10.0 cm, what will be the amplitude after 44.0 oscillations?
b.) At what time will the energy be reduced to 15.0% of its initial value?
