Homework Help: Pendulum physics homework

  1. May 10, 2006 #1
    A simple pendulum is made from a 0.60 m 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?

    So would the max speed be at the bottom of the drop??? Do i need to use an energy equation of some sort?? All i know is the length of the string is .60m. I'm lost.

    Hint 1: What's the period of a simple pendulum?
    Hint 2: Is mechanical energy conserved?
