Arrow Flight Calculations
# https://colab.research.google.com/drive/1iUvsAFJ1hCD3qeSczQ7So6UYxWzrtiX5?usp=sharing
# === Arrow Ballistics Simulation ===
# This script simulates the flight of an arrow, first without fletching (vanes), then with fletching.
# It optimizes the launch angle to hit a target at 70m, logs all key parameters at each step, and plots the trajectory with fletching.
