This is a simple pendulum

the period is 60 secs

length is 894 m

I know that $\displaystyle w= \sqrt \frac g{L}$

but isnt that w rotational velocity...tho the units are m/s when you do it...i'm not sure

The units are in 1/s, so this would be an angular speed. However, this is no equation for angular speed that I've ever seen for a simple pendulum. Both the linear and angular speeds vary: they are not constant.

Is this a portion of a larger problem? If so, it might help to see the rest of the problem.

Edit: Wait, I know what is happening. The $\displaystyle \sqrt{\frac{g}{L}}$ is the angular frequency. This is NOT an angular speed.
