A weight hangs from a spring and bobs 3 inches above and below an equilibrium position. The weight takes 8 seconds to complete a full cycle (period = 8). When graphed, time is on the horizontal axis and position relative to equilibrium is on the vertical axis. Which statements are true? Check all that apply. The amplitude is 6. The graph is stretched vertically by a factor of 3. The frequency is StartFraction 1 Over 8 EndFraction. The graph is compressed horizontally by a factor of StartFraction pi Over 4 EndFraction. The frequency is 8.
