Where m is your mass (for me this is 80 kg), g is gravity (=9.8 m/s^2), p is density of fluid you’re moving through (in air p =1.225 kg/m^3), A is the project area of a human (=2 m^2 for my height) and Cd is your drag coefficiant (assume 1 for a human).

So plugging the numbers in, you get about 25 m/s or 90 km/h.

Of course…this isn’t related to your homework is it? ðŸ˜‰
