Homework Help: Physics

Posted by Anonymous on Tuesday, February 19, 2008 at 11:04am.

A simple pendulum is made from a 0.65m long string and a small ball attached to its free end. The ball is pulled to one side through a small angle and then released from rest. After the ball is released, how much time elapses before it attains its greatest speed?

I am not sure how to solve this problem. I do have the formula, but it doesn't help: 2pi(f)= sqrt(g/L)

Thanks for your help!
