More Pendulums and Energy

  1. Nov 3, 2004 #1
    I have looked through the forum here and several other forces. My task is to derive a formula to determine the angle of release of a simple pendulum. I know the mass, velocity at lowest point and I can therefore determine the height or distance it fell mgh=(mv^2)/2. I am not able to locate the geometric/trig brain cells that will let me use this information to determine the angle athough I do know the adjacent side of the similar but smaller triangle. I do not know the length of the string. Could someone point me in the right direction please?

    If you don't know the length of the string, I don't see how you can find the angle of release.

    uh-oh, that does not sound promising. Thanks anyway.
