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

I THINK that this q need more information, such as what the air resistance IS. Usually, the acceleration would be taken as that due to gravity, g, which would be about 10 m/s/s. But, this may not be a "usual case".
