• A)the amplitude is half as great and the maximum acceleration is twice as great
• B)the amplitude is twice as great and the maximum acceleration is half as great
• C)both the amplitude and the maximum acceleration are twice as great
• D)both the amplitude and the maximum acceleration are four times as great
• E)the amplitude is four times as great and the maximum acceleration is twice as great
