Five identical particles of mass m = 0.30 kg are mounted at equal intervals on a thin rod of length l = 1.01 m and mass M = 2.0 kg, with one mass at each end of the rod. If the system is rotated with angular velocity = 60 rev/min about an axis perpendicular to the rod through one of the end masses, determine(adsbygoogle = window.adsbygoogle || []).push({});

(a) the kinetic energy and

(b) the angular momentum of the system.

I have KE = 1/2*Irod*w^2 + 1/2*Iparticle*w^2

= 1/2(1/3*Mass of rod + 1/2*Mass of particles)*L^2*w^2

What am I doing wrong? I haven't looked at part b yet.
