Meriam, Kraige & Bolton — Kinetics of Systems of Particles: Problem 4_12

4/12 The two small spheres, each of mass \( m \), and their connecting rod of negligible mass are rotating about their mass center \( G \) with an angular velocity \( \omega \). At the same instant the mass center has a velocity \( v \) in the \( x \)-direction. Determine the angular momentum \( H_O \) of the assembly at the instant when \( G \) has coordinates \( x \) and \( y \).
