Yeah, It was just weird feeling a bow do that.
I haven't ever shot an arrow that heavy before and have never experienced a bow actually recoiling.
Actually, with a high enough arrow mass, when releasing the string, the arrow would remain stationary and the only acceleration would be the bow accelerating backwards!
Nope, that couldn't happen. Haven't you been reading this thread?
As the arrow weight increases, the KE of that arrow
ALWAYS goes up.
