think of a traingle
(v+a)*[(b/v)t]=b
?
e: oh wait im idiot
e2: it seems that you're right
after ordering I've got
v^2tatv+ab=0 (smth like ax^2+bx+c=0)
v= sqrt(at(at4b))at or v=sqrt(at(at4b))at
everythings seems to be ok but when i substitute letters by any numbers which solve your equation i've got v less than 0 in both cases
anyway thanks a lot :)
i guess solution 2 is the one you are looking for since its gonna be "+"
in (at(at4b)) should be "+" instead of "" and now everything is ok
thanks! If I meet you in real I'll buy you beer :)
