Extraordinarily weak(I'm not trying to be mean): My bow gets 52 fpe(240 fps, 367-grain arrow), and most adults' compounds get 70-80 fpe.

Double the velocity, quadruplethe energy.
Double projectile weight while velocity is constant, double the energy.

4-5 FPE are all that are needed to kill rabbit, but that's on impact, what I calculated is when your arrow leaves your bow.

Firearms have far more energy, .222 rem about 1000-1100 FPEup to .50 BMG with 16000 FPE. Standing within 2 metres of the impact areof the .50 I just mentioned is certain death.
