Problem 2: The pendulum shown consists of a massless rod and a sphere with a radius of \( 1 \mathrm{~m} \), a pivot to center distance of \( 5 \mathrm{~m} \), a mass of \( 120 \mathrm{~kg} \) and \( \mathrm{I}_{\mathrm{G}}=2 / 5^{*} \mathrm{~m} / \mathrm{r}^{2} \). If the pendulum is being driven only by its own weight, find its angular acceleration at the instant shown. Angular acceleration of the pendulum
