Question
An amusement park has two ferris wheels that both load passengers at the bottom, 3 m above the
ground. Both wheels require 40 seconds to complete one revolution. The larger ferris wheel has a
diameter of 25 m and the smaller ferris wheel has a diameter of 10 m. The height of a passenger on each
wheel can be expressed in the form h(t) = a cos[b(tc)] + d, where h(t) is the height above the
ground in metres t seconds after the ride begins.
