Question

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

Answer 1

v = -2.55 m/s, a = -0.02 m/s2

Step-by-step explanation:

Answer 2

That's going to depend on the length, width, height, mass, weight, density,
and moisture content of the cotton ball, as well as the length and position
of every little fiber sticking out of it.

Now you know why we always ignore air resistance in physics-of-gravity problems.
