Question

CHECK MY WORK FOR A MEDAL
1. A buoy oscillates in simple harmonic motion according to the motion of waves at sea. An observer notes that the buoy moves a total of 6 feet from its lowest point to its highest point. The frequency of the buoy is ¼ (it completes ¼ of a cycle every second). (30 points)

a. What is the amplitude of the function that models the buoy's motion?
6 feet

b. What is the period of the function that models the buoy's motion?

pi/2

c. Using cosine, write a possible equation to model the motion of the buoy.

d= 6 cos (pi/2)

Answer 1

ummmmmm
