How much kinetic energy is needed for elk?
adb:
Kinetic energy is the wrong way to think. Works for firearms, but not bows. It's all about penetration, which comes from mass and velocity, and the right broadhead.
And for bows at short distance like ours, it's mostly mass. Stickbows don't have high velocity, so the arrows need to be on the heavy side for hunting.
Think of it this way... would you rather get hit in the head by a golf ball going 50 mph, or a ping pong ball going 75 mph?
And shot placement is a given with any type of hunting. I've seen deer run away unrecovered after being shot in the a$$ by a 338 Win Mag.

Like JW said, you certainly are planning this all out ahead of time. Completely understandable since shots at elk are few and far between, even for those of us lucky enough to live in elk country.
With that being said, don't over think it. Elk are tough but if they're lungs/heart aren't able to pump blood they die like everything else. My previous neighbors kid killed a cow elk with a 35 pound recurve he found at a garage sale with an arrow he bought at Walmart to replace his other arrow. Yeah, he had one arrow to practice and hunt with. The arrow went in one side and out the other. He couldn't find the arrow and was bummed because he had to buy another one.
He got lucky in more ways than one, but i think it proves that an arrow shot from just about any weight bow is moving fast enough to have enough energy to kill just about anything.
Just my .02.

Single bevel broadheads are either right hand spin or left hand spin....just like the helical spin on your fletching. Match them and you improve penetration and bone splitting power. Mismatch and lose approx. 10% penetration power.

I wonder what the variables are in the calculation for Kinetic Energy?? Mass and Velocity? and you should always have a sharp broadhead.
Just IMHO....

Actually, if I remember my physics correctly..... Kinetic energy = 1/2 Mass X Velocity squared.... Therefore, It does has a lot to do with penetration. You both are thinking in the right direction. ;)
