Calculate the moments of inertia I and I for a uniform disk of radius R and mass M. Take the z-axis to be perpendicular to the plane of the disk and passing through its center. If the disk rotates with angular velocity ω about the z-axis, what is the rotational kinetic energy?
dm = da = adydz = ardrdθ
x = rcosθ
y = rsinθ
z = 0
