Ferris Wheel Motion Quiz

The video tutorial explains a problem involving Jacob and Emily riding a ferris wheel with a 16-meter diameter at a carnival in Billings, Montana. The instructor derives an equation for their height above the ground as a sinusoidal function of time, considering the wheel's rotation speed of 3 revolutions per minute. The process involves calculating the wheel's radius, understanding the relationship between revolutions and angles, and using trigonometry to express height as a function of time.

What is the radius of the Ferris wheel if its diameter is 16 meters?

What is the adjacent side in the triangle used to calculate the height of Jacob and Emily?

• h

• 9 - h

• 8

• 18t

What is the final expression for the height h as a function of time t?

• h = 8 - 9 cos(18t)

• h = 9 - 8 cos(18t)

• h = 9 - 8 sin(18t)

• h = 8 + 9 cos(18t)

What is the maximum height Jacob and Emily can reach on the Ferris wheel?

• 17 meters

• 16 meters

• 9 meters

• 8 meters
