t= time
a = acceleration
and figuring out that t=7
you have:
0 = v*7+.5*(-9.8)*7^2
which got me
v= 34.3 m/s
have no idea if that's actually right though

Ah yes, that makes sense.
Seeing the equation written that way (instead of the way my professor wrote it) makes things a lot easier. It's just a matter of plug and play then.
