"Everyone knows that if we drop an iron bar and a feather from the same height at the same time, the iron bar will hit the ground first.
Here the factor that stops the feather is not air friction, but the air simply blocking its movement. The air also affects the iron bar, but not as much as it does the feather.
If there was no air around us, absolutely everything will hit the ground simultaneously, regardless of it's density, weight, shape, orientation etc. But, in air, it will slightly depend on the aforementioned factors.
A dense, well-shaped object with no air inside will fall more efficiently than, say, a feather, which has low density and a ""bad shape"" for movement in air.
t = sqrt of 2h / g
so from your data if we take g=10m/s2
t=√20/10
t=√2
t=1.414 second
