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

kgm2

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

m

(c) Calculate the period of oscillation.

s

First, since this seems like a simple pendulum, I calculated the time of oscillation using the equation T = 2pi SqRt(l/g)

T = 2pi SwRt(0.5/9.81)

T = 1.4185 s which was incorrect.

Once I had the time of oscillation, I was plannning on finding the center of mass using the equation I = T^2MgR/4pi^2

Can someone please help me find the time for oscilation and tell me if my second thoughts are correct.
