Since the radius of the wheel is 7 feet, point P goes 7 feet above and below the center of the wheel. From this information, you can find the amplitude. Write the value of this constant.

To find the amplitude, we need to know the definition of amplitude in relation to a wave or oscillating motion. Amplitude typically refers to the maximum displacement of the wave or the maximum value of the quantity being oscillated.

However, in this case, you mentioned the radius of a wheel and point P going above and below the center of the wheel. From this information alone, we cannot directly determine the amplitude of a wave or oscillation, as we do not have any information regarding any specific wave or motion.

If you could provide more context or clarify the question, I would be happy to help you further.
