To register at http://www.box2d.org/forum/index.php there are difficult and annoying questions. But I solved one of them which was easiest for me, so I share in case someone else will want to register there:
A ball of mass 3 kilograms begins falling with gravity of 10 meters per second squared. How many meters does it fall in 8 seconds?
use formula:
s = (t^2 *a)/ 2 - ut
s - distance
u - initial velocity
v - end velocity
t - time
so the answer is 320
