A simple pendulum is made from a 0.653 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?
incase that didn't come out right using the symbols: Timeofpend=2pi*the square root of length divided by gravity
The Attempt at a Solution
I used this equation from notes in class and the answer was wrong... I'm not sure whether you need to factor in kinetic energy/potential energy because it's asking the time before it attains the greatest speed or not. I feel like this should be an easy question. Thanks ahead of time! :-)
