1. The problem statement, all variables and given/known data A simple pendulum is made from a 0.67 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? 2. Relevant equations f=frequency f=(1/2pi)(g/L)^.5 f=1/T where T=period 3. The attempt at a solution f=1/T f=(1/2pi)((9.8m/s^2)/0.67m))^.5 f=6.007 f=1/T 6.007=1/T T=1/6.007 T=.166s This is the answer that i got but it is wrong and i do not know why, and now how to do it if this is the wrong way.
