Hi, Folks.
As I understand it, terminal velocity for most objects -- except pages of paper, feathers, etc. -- is around 120 mph. I have this faint suspicion that if even something as light as a penny hits you at 120 mph, you ARE going to know about it.

As for the bullet attaining muzzle velocity, let's assume a muzzle velocity of 1,500 fps, x 60(seconds), x 60(minutes), divided by 5280(feet per mile) = 1,022.72 mph. (That distance is not going to be attained because of air resistance.)

I VERY seriously doubt that ANYTHING falling from ANY height within the Earth's atmosphere is going to attain that sort of speed. If my calcs are correct -- and I'm NO maths genius -- terminal velocity, 120 mph, translates to 176 fps, just a little short of the above assumed 1,500 fps muzzle velocity.

Anybody got any corrections here? I'm always open to learning.

You have a wonderful day. Best wishes. Deas Plant.
