Two identical hockey pucks of mass m = 0.1 kg slide towards each other along parallel trajectories on a horizontal patch of frictionless ice, as shown. The pucks have initial velocities 1ˆ2.0vj=− m/s and 2ˆ3.0vj= m/s. At time t, they collide with a massless rigid rod which is lying on the ice, and stick to it, a distance d = 2.0 m apart. Immediately after the collision, what is the angular speed of this rotating system?
