﻿ Free fall with air resistance
Free fall with air resistance none linear model    Fd = f(v2)

System of units:
 Example: Find the final velocity of a skydiver falling from a height of 2000 meter the mass of the skydiver is 72 kilogram and the air resistance is 0.24 kilogram per meter. Example: An object with a mass of 0.15 kg is dropped from a height of 1 km, given that the air resistance is 0.24 kg/m. Find the terminal velocity and the falling time. Example: Find the drag force acting on an object travalling at a speed of 50 m/s in air whose density is 1.29 kg/m3 the drag coefficient is 0.5 and the frontal area of the object is 0.8 m2.
