Physics final today!! Challenging problem! Edit: SOLVED!

[yhelothar]

I just figured it out...
Man I should've remembered the pendulum formula, it would've saved me so much trouble.
blueshoe, your formula was almost right, except it ends with sqrt of L/g, instead of g/L
Solve for g, and coicidently, it turns out to be 9.8m/s
I wasted like 2 hrs on this problem.

blueshoe, even though your formula was wrong, you put in the effort and was almost there, so I'll paypal you $3. So give me your paypal account, and I'll send you the cash.

Ohhh...*bangs head on table*
Whoops. I knew that g didn't make sense. Oh well, good luck on your final.

Anyways, I googled the definition you provided, and I found this weird site that had a definition, and I tried to work it out, and I got a pretty reasonable number.
T=2Pi/w ; w=sqrt(g/L)
By using that, I got 6.35m/s²

Actually that sounds right. I knew there was an easy equation out there for this.
