Five identical particles of mass m = 0.30 kg are mounted at equal intervals on a thin rod of length scripted l = 1.13 m and mass M = 2.4 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 the following.
(a) the kinetic energy of the system
kg·(m/s)2
(b) the angular momentum of the system
kg·m2/s
