>>190790077>thinking someone couldn't go limp to minimize the damage>thinking people haven't done this from much greater heights>multiplying acceleration times time and expecting an accurate answer did you grow up in a bubble? did you drop out of school? you have to be pretty sheltered to not know about people learning how to fall from even higher than what you described, as well as fuck up your units on gravity and not use the proper kinematic equation..
for starters, 9.81m/s is a velocity, not a goddamn acceleration.
Source for equation:

First of all we don't know how long it takes them to fall. That's fine because there's a kinematic equation that handles that and only needs the information we already have:
v,final^2 = v,original^2 +2a(x,final - x,original)
v,original = 0 (start of the fall)
a = 9.81 m/s^2
x,final - x,original = 3m
So given what we know
v,final^2 = 0^2 +2a(3m)
v,final^2 = 0 +2(9.81m/s^2)(3m)
v,final^2 = 2(9.81m/s^2)(3m)
2(9.81m/s^2)(3m) = 58.86 m^2/s^2
therefore
v,final^2 = 58.86 m^2/s^2
sqrt(v,final^2) = sqrt(58.86 m^2/s^2)
therefore
v,final =7.67 m/s
7.67 m/s * 3600s/hr = 27,619 m/hr = 27.619 km/hr
You're a fucking idiot. Don't quit school or your day job.
