39. A Bobbing Cork A cork floating in a lake is bobbing in sim- ple harmonic motion. Its displacement above the bottom of the lake is modeled by y = 0.2 cos 20nt + 8 where y is measured in meters and t is measured in minutes. (a) Find the frequency of the motion of the cork. (b) Sketch a graph of y. (c) Find the maximum displacement of the cork above the lake bottom.
