I need help with following questions please.

A2. A physical pendulum consists of a rod of length 0.6 m and mass mr = 380 g attached and one end to a solid sphere of radius 0.15 m and mass me = 725 g, and to the ceiling on the other end. a) Calculate the moment of inertia, I, for the pendulum. b) Assuming both the rod and sphere are of uniform densities, determine the position of the center of mass (relative to the ceiling). Equation is Xcom - Mtotal 1Emiri. c) What is the period of its motion? d) If the sphere is detached, calculate the period of just the rod as it swings. e) For comparison, calculate the period of a simple pendulum with a length of 0.75 m and a bob mass of 1.105 kg
