Consider the following problem: (this isn't homework, I thought this problem up myself and I'm wondering how to do it)(adsbygoogle = window.adsbygoogle || []).push({});

-------------------------------------

You have a simple pendulum of mass M and a radius R, which is released from the horizontal. How much time does it take to reach the lowest point, as a function of R?

-------------------------------------

It's easy to find the velocity as a function of the angle, but I couldn't figure out a way to factor time into it. There is also an approximation of the period of an osscilating pendulum which is equal to 2pi*root(L/g), but that holds only for small angle values.

So how do you do it?
