Suppose a buoy oscillates in a simple harmonic motion as the waves go past. It is noted that the buoy moves a total of 6 feet from its low point to its high point (see figure), and that it returns to its high point every 12 seconds. Let the function h(t) denote the height (in feet) of the buoy above equilibrium at any time t in seconds. (a) (2.5 points) Use the given information to draw at least one period of the graph of y = h(t). Assume that t = 0 is one of the times in which the buoy is at a high point. (b) (1.5 points) Write the function h(t).
