Okay, I have this equation and I want to solve for v, so basicaly it's really just an algebra problem.(adsbygoogle = window.adsbygoogle || []).push({});

Original equation

20=(v)sin(35)*(159/v)+.5(-9.8)(159/v)^2

v^2=(sin(35)(159)+.5(-9.8)(159^2))/20<-- what I do, then I take it to the ^(1/2)

The answer should be 42, but I keep getting crazy answeres. What am I doing wrong?

thanks
