7. Steamboat Problem Mark Twain sat on the deck of a river steamboat. As the paddlewheel turned, a point on the paddle blade moved in such a way that its distance, d, from the water's surface was a sinusoidal function of time. When his stopwatch read 2 s, the point was at its highest, 18 ft above the waters surface. The wheels diameter was 22 ft, and it completed a revolution everv 10 s a. Sketch a graph of this sinusoid. b. Write an equation of the sinusoid.
