1. The problem statement, all variables and given/known data Christy has a grandfather clock with a pendulum that is 1.070 m long. (a) If the pendulum is modeled as a simple pendulum, what would be the period? Already solved (b) Christy observes the actual period of the clock, and finds that it is 1.20% faster than that for a simple pendulum that is 1.070 m long. If Christy models the pendulum as two objects, a 1.070-m uniform thin rod and a point mass located 1.070 m from the axis of rotation, what percentage of the total mass of the pendulum is in the uniform thin rod? Need help 2. Relevant equations (a) T=2pi sqrt(L/g) (b) Couldn't find an appropriate equation in my textbook. 3. The attempt at a solution (a) T=2pi sqrt(1.070m/9.8m/s^2)=2.08 s (b) I don't have a clue about the equation that correspond to this part of the problem,no similar examples or anything in my textbook. To start a equation would be great, because I have percentages and meters and they want me to calculate total mass of a pendulum. Any help is great thank you.
