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 = 4.50 kg and m2 = 3.00 kg are connected to the ends of the rod. Two masses m1 and m2 are connected by a rod of length ℓ centered on the origin of an x y coordinate plane. The rod is rotating counterclockwise about the origin such that the masses each have tangential velocity vector v.Adashed circle outlines the path of the masses.   (a) Neglecting the mass of the rod, what is the system's kinetic energy when its angular speed is 2.00 rad/s?(b) Repeat the problem, assuming the mass of the rod is taken to be 2.10 kg.
