48 m/s is at 55 meters. Point blank the velocity of the arrow is 54.7 m/s. Mark Stretton shot a 102 gram arrow over a chronograph at 54.7 m/s with a 140 lb high alpine yew longbow. Simon Stanley shot a 95.9 gram arrow at 53.3 m/s with a 150 lb Oregon yew bow. The arrow retained 43.3 m/s at...

haruspex I was wondering about that too. At first I thought that I should just calculate it as a pendulum with a 3 kg helmet and a 5 kg head as one object with the arrow stuck in the head. With a closer look, I don't think that is accurate. The liner is like the liner in a hard hat. An arrow...

This is not homework. I have no idea why it was moved to this forum. I worded that question. I am currently writing on a calculator in excel on arrow trajectory and air resistance using the Euler/trapezoid method. As of now it takes 3 seconds to do all the calculations. I will combine this with...

A 0.1 kg arrow is moving at 48 m/s to the right and strike a 3 kg object (helmet resting on a 5 kg head) moving to the left towards the arrow at 9 m/s (full mounted charge). It takes 80 Joules to penetrate the 3 kg helmet, what is the velocity of the arrow after penetration when it slams into...

The slower arrow had a rhombic or lozenge cross section, significantly bigger than the lighter arrow. The lighter arrow had a relatively small square head. The Vickers plate hardness was the same. The reason for a lozenge cross section is two sharp edges to slice through the arming doublet...

Thank you. I'm interested because of military history and experimental archaeology. My interest is how heavy arrows effect armor penetration and the relationship between kinetic energy and momentum. Or whatever else is at work. I want to make a chart like the one I posted for every arrow...

This question is about the English Warbow in use during the War of Scottish Independence, Hundred Years War and War of the Roses. In 1545, way past the heyday of the Warbow, Mary Rose sank in the English channel. In 1981 they salvaged her. What they found was extraordinary. She carried 250...
