I need help with only number 2

A Ferris wheel has a radius of 20 m and rotates at the rate of one revolution every 100 s. At the bottom of the ride, the passengers are 5 m above the ground. a) Determine the equation of a cosine function that represents the height, h, above the ground at any time, t. Assume that the ride starts at the bottom of the wheel. [3 Marks] b) Sketch the function showing two cycles of the Ferris wheel.
