    Speed of pendulum

    This is a simple pendulum
    the period is 60 secs
    length is 894 m
    I know that 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 \sqrt{\frac{g}{L}} is the angular frequency. This is NOT an angular speed.
