The motion of a simple spring hanging from the ceiling can be modeled with a cosine function. the bottom of the spring has a maximum height of 7 feet 4 inches and a minimum height of 6 feet 2 inches from the floor. it takes 2 seconds for the spring to expand from its minimum length to its maximum length. what is a cosine function that models the spring’s length in inches above and below its average, resting position? express the model as a function of time in seconds

Step-by-step explanation:

Givn that the motion of a simple spring hanging from the ceiling can be modeled with a cosine function. The bottom of the spring has a maximum height of 7 feet 4 inches and a minimum height of 6 feet 2 inches from the floor. It takes 2 seconds for the spring to expand from its minimum length to its maximum length.

Middle line = average of 7'4" amd 6'2"

=6'9"

Amplitude = 7'4"-6;9"

= 7"

Hence the corresponding cosine function would be

x divided by 8=y

step-by-step explanation:

i think the correct option is the second option.
