A traditional bow with a pulling force of 40 kg can shoot through a pine board with a thickness of 100 meters.
40kg is about 88. 1 kg, 150m can shoot pine about 3cm, and 65-degree projectile is about 300m m. If the gravitational potential energy is converted into kinetic energy, if the arrow tip reduces the resistance, then about 6cm is not a problem, provided that you can shoot accurately and can't pull the heavy bow.
