I've never worked with air resistance before so any help just getting me started would be much appreciated.
A 20 kg object falls free from a height of 15 m. Including air resistance, what will its position be after 0.6 seconds? Air density is 1.11 kg/m^3.
The only equation I know for this is d = 0.5 * g * t^2
and I don't know if there are any equations for air resistance. And does air density have anything to do with this at all?
Well, I don't really know how to deal with air resistance since we haven't gone through that and still our teacher wants us to solve this. :uhh:
