A buoy in the ocean is bobbing up and down in harmonic motion. At time = 2 seconds, the buoy is at its high point, 2.8 feet above the flat ocean surface; it returns to that high point every 10 seconds. The buoy moves a total of 3.6 feet from its high point to its low point. Sketch a graph for this situation. Write a sinusoidal model that represents this situation. How high is the buoy at time = 30 seconds? Is it rising or falling at that time?
