Alright, I need this information not for science homework, but for writing a short story. You see, I am very particular about the tiny details, and in the story there is going to be a superhuman jumping off a building.(adsbygoogle = window.adsbygoogle || []).push({});

I want to know the speed of such a jump to dramatise the description, but I have no idea how to calculate it. With the limited knowledge of v=d/t and f=ma and some sketchy understanding of terminal velocity (from thesimpleto understand wikipedia), I doubt I ever will find the solution without help.

Suppose the height of the building to be 410 metres, the weight of the person jumping to be of an average adult male (I have no idea of this), the jump to be roughly straight down, and the wind to be calm.

I have no idea what drag coefficient is, so I can't say, and as for the projected area... just assume that he isn't moving very much? (And is the projected area measured at the feet or the body width?)

Hopefully I have provided enough information to calculate the speed. If not, just make up the numbers, and provide the workings, and if possible, explantions. (Extra, comprehendable, knowledge is always fun and useful)

Thank you. :D
