The wheel rotates once every 1.46 seconds and the bottom 0.3 m of the wheel is submerged in water. (Consider the water surface to be the x-axis) a) Determine the cosine equation of the graph, starting from a point at the top of the wheel. b) Graph the height of a point on the wheel relative to the surface of the water, starting from the highest point. c) How long is a point on the wheel underwater? 4. The bottom of a windmill is 8 m above the ground, and the top is 22 m above the ground. The wheel rotates once every five seconds. a) Determine the cosine equation of the graph, starting from a point at the bottom of the windmill. b) Draw the graph of two complete cycles. c) What is the height of the point after 4 seconds? d) For how long (over the course of both cycles) is the point above 17 m? 5. A point...
