Projectile motion

This repo is my proposed solution to the below challenge.

The challenge

• whenever a user clicks the page / container, create a projectile (example ball) with properties
  • random colour
  • random size between 50 and 100px
• as soon as the projectile is created it is launched with:
  • random velocity
  • random trajectory
• everytime the projectile hits a delimiter of the page / container its velocity is reduced
  • top and bottom delimiter influence the y velocity
  • left and right delimiter influence the x velocity

Documentation

Equations

• X = Xinicial + Vx * T
• Y = Yinicial + Vinicial _ T - 0.5 _ A * T2

Velocity equations

• Vx = constant
• Vy = -V * T

Constants:

• T - Time
• A - Gravity acceleration

How to run

• npm i: install dependencies
• npm start: run the application
• npm test: run the tests
