ballistics with air drag

Controls

Launch a projectile and see how angle, speed, and air resistance shape the arc.

Range46.1 m

Max height16.1 m

Drag modelquadratic

Governing equation

\overset{v}{˙}_{x} = - 0.02 v v_{x}, \overset{v}{˙}_{y} = - 30 - 0.02 v v_{y}

Reading this result: With this much air drag the range-optimal angle falls below 45° (toward ~35°), and the descent is steeper than the climb.
