nevermind

For some reason, I can't find this anywhere, and it seems as though it should be painfully easy.

I have a simple pendulum. I've found the length, the time is given, and it's "at a position such that g = 9.80m/s^2." I have to find how many complete oscillations it makes in that given time.

??? thanks guys.

edit nevermind, got it.

 

[Legendary]

Time given / T = # of oscillations
T = 2*pi*(L/g)^(1/2)
Where L is the length of the string

Figure out the period. which is related to frequency. Which is related to K, I believe. If you can't figure it out, I'm doing my physics HW in a few minutes and I will get you the actual formula.
