A spring with a mass attached at the end oscillates with maximum amplitude of 8 cm (over 3 inches). Its decay half-time is 12 seconds. (a) How long will it take the spring’s vibration to decay to the point where its amplitude is 2 cm? (b) What will the amplitude of the oscillation be after one minute?
