As you ride a ferris wheel, your distance from the ground varies sinusoidally with time. You enter the ferris wheel from the bottom, which is 8 feet from the ground. The ferris wheel has a diameter of 60 feet and makes a full revolution every minute. What is your height above the ground at t = 20 seconds?

a. 46 ft
b. 47 ft
c. 53 ft
d. 54 ft

Impatient much?
