Unformatted text preview: A Ferris wheel has a radius of 35 m and starts 2 m above the ground. It rotates once every 53 seconds. a) Determine the cosine equation of the graph, if the rider gets on at the lowest point. b) Sketch two complete cycles of a graph representing the height of a rider above the ground, assuming the
rider gets on the Ferris wheel at the lowest point. c) What is the height of the rider at 81 seconds? d) At what time does the rider first reach a height of 51 m? 2. A Ferris wheel makes 4 revolutions in one minute. The diameter of the Ferris wheel is 28 m, and a rider boards
from a platform at a height of 30 m above the ground. The ride lasts 30 seconds. a) Determine the cosine equation. (Hint: Think about where the rider is starting in this question.) b) Sketch the graph for the complete ride. c) At what times is the rider at a height of 20 m? Pre – Calculus Math 40S: Explained!
