I just add this new forum a few days ago. So you are the first one to ask for new simulations.
Actually, I have created one with k*v[sup]2[/sup] many years ago. You can find it at [url=http://www.phy.ntnu.edu.tw/ntnujava/index.php?topic=145.0]Projectile Motion with Air Drag[/url].
In the above simulation I have created, you find find I use a very large initial velocity and the scale was in unit of km.
Due to your request, I am going to create a new which you can select the air resistance to be either k1*v or k2*v[sup]2[/sup].
k1 and k2 are not the same dimension. And if you just changed the formula from k*v to k*v[sup]2[/sup]. Because the air resistor become so large, it will stop very shortly. And you might not see the object moving. (May be that is the reason why you did not see the effect)
I will post it soon when it is done.
