As you ride the Ferris wheel at the park, your distance from the ground varies sinusoidally with time. You start a stopwatch, when the time reads 50 seconds, your seat is at the highest point on the wheel. Let + be the number of seconds that have elapsed since the Ferris wheel started.

You find that it takes you 110 seconds to make a complete revolution. The diameter of the wheel is 60 feet and sits 3 feet above the ground.
A. Write an equation: y=
B. Determine the time you will be 40 feet above the ground for the second time

Answer:

The equation for the Ferris wheel is y=60sin(2π/110)(x-50)-3. The time you will be 40 feet above the ground for the second time is approximately 125.7 seconds
