Geschwindigkeit bei Sturz aus Hoehe Speed in falls from height
Model assumptions:g=9,8 m/s2 h=height d=distance from structure temp = temperature [deg C] m = mass [kg] vt (terminal velocity) = sqrt(2mg/C*rho*A) with C (numerical drag coefficient) = 0.5 (spherical) to 2.0 (irregular) A (cross sectional area) = 0,2 (feet first) to 0,7 (stretched out) [m^2], rho = air density approximated using quadratic fit = 2E-05*temp^2 - 0.0048 * temp + 1.2924, tau (characteristic time) = vt/g, t impact (time to impact) = tau * acosh (exp(h / (vt * tau)), v impact (speed at impact) = vt * sqrt ( 1- exp (-2gh/vt^2)), at (additional time used for 50 cm jump) = 2 * sqrt (2 * 0.4 * g)) [link]
