Overview

This is a small application written in ruby that does calculations on kinetic energy, momentum, and the types of game that can successfully be taken with that system.

Code Example

There are only two classes in the application (not including the tests). Arrow and Bow. The Arrow class takes an arrow's weight in grains and a bow object (or any object that responds to a "speed" method). The bow has only one attribute which is "speed" in feet per second. Most archer's know the speed of their bow and the weight of their arrows. Given a bow speed and arrow weight, you can calculate the KE and momentum. The type of game that can be taken is based off of the KE and a chart found on Carbon Arrow University.

  bow = Bow.new(250)
  arrow = Arrow.new(400, bow)

  arrow.kinetic_energy
  arrow.momentum
  arrow.game_type

Motivation

I wrote this application as a test and a learning experience. I'm an avid hunter, specifically a bowhunter, and so I use the math all the time. I'm also learning more about OOD and wanted to try a small project that uses single responsibilty and dependency injection. I also wanted more practice with writing tests. So... That's why the project exists.

Installation

Just clone or obtain however you'd like, open a terminal window in the project's directory, and type ruby interface.rb. You'll be prompted by the interface to run the script.
