A skydiver of mass m in a vertical free fall experiences an aerodynamic drag force F$\_$D$=$C$\_$D$^2,$ where y is measured downward from the start of the fall. The differential equation describing the fall is y$=$g$-$C$\_$D$/$m$^2.$ Determine the approximate time of a $5$m fall. Use g$=9\mathrm{.}80665$m $/$ s$^2,$ C$\_$D$=0\mathrm{.}2028$kg $/$ m and m$=80$kg$.$ solve with a numerical methods in python code
