The Colossus ferris wheel at Six Flags St. Louis has a diameter of 50.3 m. A rider located on the circumference of the ferris wheel rotates at a speed of 16 km/h.
(a) What is the angular speed of the ferris wheel, in rad/sec?
(b) How long does it take for the ferris wheel to go through one full rotation?
(c) There is a bird sitting on the mid-span of one
of the ferris wheel support beams. How fast is the bird moving, in km/h?

(a) v = rω
You have v and r, so plug 'em in
(b) ω = 2πf ... the period t = 1/f
(c) halfway out, half the speed.

im confused on what does f represent

f is the frequency. That is, how many revolutions per hour (or minute, or whatever)
Looks like you have some studying to do, if even that is confusing.
