1. The problem statement, all variables and given/known data https://aapt.org/physicsteam/2010/upload/2009_F-maSolutions.pdf # 18 2. Relevant equations T = 2∏√(L/g) 3. The attempt at a solution Honestly, I'm not sure how at all to do this question. All I know that the distance from the small peg to mass m is L/3 - so that should be accounted for. What throws me off is how the pendulum starts of rotating about the small peg and should end up rotating about the fixed pivot point. I don't know how to represent that in equation.
