The following function is used to determine a parachute’s falling velocity. Consider the function to determine its root, the drag coefficient, c such that the velocity, v is 40 m/s after a free-falling time (t) of 10 second. f(c)=(gm/c)(1-e^(-(c/m)t))-v g = gravitational acceleration = 9.81 m/s2 m = mass = 68.1 kg
