A pendulum consists of a uniform disk with radius r = 10 cm and mass 480 g attached to a uniform rod with length L = 500 mm and mass 175 g.

(a) Calculate the rotational inertia of the pendulum about the pivot.

(b) What is the distance between the pivot and the center of mass of the pendulum?

(c) Calculate the period of oscillation.

(i have absolutely no idea how to do this) thanks..

On a, use the parallel axis theorem.
on b, I assume it is 60 cm. Use pendulum formulaa on c.

I will be happy to critique your work.
