Did we get this solved yet?

A bullet fired and a bullet dropped at the same time
Which bullet or bullets will hit the ground first?
Which bullet or bullets will hit the ground first?

High Speed camera will show 2 bullets racing towards the ground
A photo finish ~(.)-(.)~
Bullet 1 got the speed but has to travel
Bullet 2 is a lazy bullet but a short fall
Bullets 1 and 2 hitting at the same time is a Physics Professor's YES
What do u say???????????
However fired level over a calm body of water and both bullets of equal distance from the ground, with the bullet drop as the fired bullet exits the muzzle,we all know that answer. Not factoring in the curvature of the earth of course and the speed of the fired bullet.
If the bullet fired is fired paralell to the ground and they are fired and dropped at the exact same height and time they will impact the ground at the same time.
I don't think so [:D]
My high school science teacher did even own a gun and never seen a bullet. So what did she know
I away argued this with her and she all ways gave me an F for that answer
O! how I liked her.[:)] I only wish she was around so I could show her she was wrong
And it only took 70 years to prove she was wrong

,,,,check out Myth Busters video,,,,,Fired Bullet vs. Dropped Bullet,,,,,they concluded the difference is 39.6 milliseconds,,,,,,
Wallie,,,,,ya beat me to it!!!!!,,,,,,,[:D][;)]

Earth curvature
yep, there are a host of factors involved that could make one drop take longer than the other.
And fiery auto crashes
Some will die in hot pursuit
While sifting through my ashes
Some will fall in love with life
And drink it from a fountain
That is pouring like an avalanche
Coming down the mountain
Exact same height.
Exact same timing. (Tail of projectile leaving the muzzle.)
Perfectly level surface.
In a vacuum. (Bullets at speed have some flight characteristics.)
Same time given...

yet we don't live in an environment where any of that is possible. So, not "same time". [:D]

Now, do to 'rigidity in space', I'd vote for the dropped bullet UNLESS you fired the bullet W/O any spin imparted to it. Then it would be a tie.
Thanks for your time, Joe

While they are spinning, they are making their own gravity, and thusly reducing the impact of earth's gravity.
BS ALERT!
They hit the ground at the same time. Mythbusters must have been off a bit. [8D]
Yep, as long as all other factors are the same excluding weight of bullet they will hit the ground at the same time.
It was listed in the NRA Firearms Fact Book with the right answer
This is a tricky quiz
I got F in High school [B)]
I got A on GunBrokers Twice [8D]
I got A on a European sight 5 times [8D]
I got A on the sewing forum [8D]
I got A on the cooking forum [8D]
I was right and no one believed me
And still they don't [:(!]

Okay, maybe I'm describing it wrong. So You explain to me why the gyroscope will maintain a 'set' in space, and wont move, much as a child's gyroscope overcoming earth's gravity while it is tilted at, say, a 45deg. angle. Back to you. Joe

force is distinct from gravity. Gravity is a function of a body's size. So the spinning object experiences and may impart many translational forces, it does not create gravity.

Mr. P..thanks. Excellent cause factor as to why my original statement stands, and the spinning object will not reach the ground prior to, or at the same time as the non-spinning object? Can I run with that assumption? Tks, Joe
A spinning gyroscope will seemingly resist gravity if supported on one end.
It may stick out horizontally "unsupported"
If it is not supported at either end, it falls as fast as a non rotating gyroscope.
What it has is an extreme rotational inertia. It will fall just as fast, but if you support it only on one end, it will not perceptibly rotate along its axis.
Get a gyroscope, spin it up, hold it in your hand, note you can raise and lower it as normal, now try twisting it and rotating it - now it will feel "weird"
I also noticed that rig they set up allowed the gun muzzle to rise during recoil.
Even if they had exact boresighting, it may be that the movement from recoil during the time the bullet is traversing the barrel is sufficient to explain a difference of about 39 milliseconds.

Strange, but I believe that's exactly what I said.[:)]
