A light rod of length ℓ = 1.00 m rotates about an axis perpendicular to its length and passing through its center as in the figure below. Two particles of masses m1 = 4.45 kg and m2 = 3.00 kg are connected to the ends of the rod.
(a) Neglecting the mass of the rod, what is the system's kinetic energy when its angular speed is 2.20 rad/s? The correct answer is not zero. J
(b) Repeat the problem, assuming the mass of the rod is taken to be 2.30 kg.
