Need a bit of help with arrow speed.

[wateroksnmud]

Hi! To start off I am an archer. I'm currently a freshmen working towards my degree but have not yet made it to physics. The issue is that I need to create a calculator that I can use to find the speed of an arrow being shot from a bow when I have X (the weight behind the string) and Y (the weight of the arrow in grains). Where do I even start?

I have read some of the posts in here as I love math and would love to do this myself, but a lot of the formula's look like hieroglyphics right now.

This is calculator is not homework but for a site I'm building. You can see it nolimitsarchery.com

I appreciate any help in advance.

Archery seems to be one of those sports that attracts physicsts - and so

Hello! As a fellow scientist and archer, I would be happy to help you with your calculator. The first thing you need to know is that the speed of the arrow is determined by several factors, including the weight of the arrow, the weight behind the string, and the bow's draw weight. To calculate the speed, you will need to use a formula called the "arrow speed formula," which takes into account all of these factors.

The formula is: Arrow Speed = (Weight behind the string / (Arrow weight x Bow's draw weight)) x 225. Your weight measurements should be in the same unit (either pounds or kilograms) for accurate results.

To make things easier, you can use an online calculator or a spreadsheet to plug in your numbers and get the arrow speed. There are also apps available for download that can do this calculation for you.

I understand that the formula may seem daunting at first, but with a little practice and understanding of the variables involved, you should be able to use it effectively. If you have any further questions or need clarification, please don't hesitate to reach out. Happy shooting!
