When the project starts, then you type the speed (or magnitude) of the arrow. Then, enter the angle the arrow will be traveling at (in degrees). Then watch it travel across the screen. An angle less than 90 degrees would be fine. Also, a speed of more than 75 pixels/second but less than 250 pixels/second is recommended.
I know physics and I used the calculations and formulas in the code. I had to use the British units (sorry metric system, your units are too small), for the acceleration and I used some trig too. However, the angle is still kind of wonky and this simulator is kind of slow. I'll fix that later.
