Question

The pendulum shown in (Figure 1) is pulled to a 25 angle on the left side and released Part A What is the period of this pendulum? Express your answer with the appropriate units Ttot-Value Units igure 1 of 1 Submit Request Answer Part B 12 cm What is the pendulum's maximum angle on the right side? Peg 12 cm Submit Request Answer

Answer 1

$T=\pi\sqrt{\frac{0.12}{9.81}}+\pi\sqrt{\frac{0.12\times2}{9.81}}=0.838~\text{seconds} \\ \\ (B)\text{By using the conservation of energy} \\ mg\frac{l}{2}(1-cos25)=mgl(1-cos\theta) \\ \\ \theta=17.60^\circ$
