If a cotton ball is dropped from 12 meters with air resistance, what will be the velocity and acceleration at t = 1.00 s?

That depends on the weight, shape, size, density, and moisture content of the cotton ball, as well as on the length, shape, thickness, and surfacetexture of every little cotton fiber sticking out of it.Now you know why we typically ignore air resistance when we work with objects falling in gravity.
