How far can I shoot a deer before penetration becomes an issue?

[7 Lakes]

Maybe I can help, in 1974 I started college as a Physics major until I found out just how dumb I really was.

Generally speaking an object will fall at 9.8 meters/sec. squared.  

If you shoot an arrow into the air and it takes 5 seconds to fall from it highest point, this formula does not take into account any forward momentum just the force of gravity.

Say the arrow falls for 5 seconds @ 9.8 meters per second squared which means the object hits the ground at 49 meters per second.

Converting meters/sec to feet/sec. 49 meters/sec is equal to 160.7612/ feet per second which is plenty fast enough to pass through a deer.  

If I remember correctly you should also add the velocity of the object at apogee (highest point).  Possibly 150'/sec on a 45 degree shot.

Now if I have the 5 second falling time & the 150'/second current velocity correct you have an arrow traveling at 310'/second.  

More than enough to pass through almost anything living.  

Don't bet the farm on this math. As Kenny is fond of saying... "Your mileage may vary"

Have a nice day

Ooops, I'm sorry, I forgot to let everyone know they should not shoot an arrow into the air in hopes that a deer will walk under it 5 seconds later.

This was from Wikipedia, I was kinda close

This is only true in a vacuum though. It doesn't take drag into account.

Don't forget to take the coriolis effect into account.

You know, when I opened this thread I thought I was asking a simple question....  

[JohnnyWayne]

Play the lottery tonight, you just might hit it    

[Slim]

Never been that lucky JW...

Slim, your question was answered in the very first post. I don't know why there are 6 pages of post on your simple question    

Of course, I just brought it back up for another round  :D

[atatarpm]

Wow I feel sorry for you Slim. The same thing happened to me on the topic of my bow

[Slim]

I'm calling it a learning experience. But,you know, there were a lot of good answers in all that too.

[atatarpm]

Yea, your right about that. But, one does wish that those who seamingly try to hyjack a thread to thier own purpose or ideas about what they think are the rights and wrongs of things would start thier own threads on thier subjects. Just seams to me that that would be more respectful too all of us.
Have a great day Ric

So,  what is the answer ?  How far can you shoot a deer before penetration becomes an issue ?

Read the posts Chuck and make your own mind up. I'm done with this one.

Hate to say I told you so...

To answer the OP directly; Optimum angle to launch a projectile for max range is 45 degrees assuming a level playing field, no wind scenario.   So given the sin cos, of the earths rotation,  and Coriolis effect based upon your direction of launch and the latitude of the location of the said launch, you can plainly see that depending on shaft diameter, max spin rate imparted by the fetching and the external drag coefficient of the said projectile, the velocity in fps, weight of projectile and the particular internal ballistic coefficient , you can PLAINLY SEE.......it depends.

Sorry couldn't resist.  Don't hate me!

It's very simple. Scissors cuts paper, paper covers rock, rock crushes lizard, lizard poisons Spock, Spock smashes scissors, scissors decapitates lizard, lizard eats paper, paper disproves Spock, Spock vaporizes rock, and—as it always has—rock crushes scissors
 
@Slim- at least you got your post count up some:)

As far as the bow can shoot.  If the arrow is in the air, it's lethal.  Plain and simple.

Just don't use flu flu's !

[MT Longbow]

And what's more, if you recall Howard Hill had a confirmed kill on an Elk at 185 yards.  It took 3 shots , under over and then into , but that elk died.  So as you can see, on the more serious note , I'll quit joking around,  like the other guys said , really , if it's in the air,  and not a draggy arrow like a flu flu, then given enough arrow weight a really long shot is still plenty deadly.

How does that advertisement go?  :confused:    :confused:  Oh yea "Let it go Louie"
