A 1.2 m long 1.7 kg horizontal rod is able to pivot regarding one end. A 35 gm bullet strikes and becomes embedded in the rod at its other end. The bullet is originally moving at 250 m/s and the rod is initially stationary. What is the angular speed of the rod/bullet combination just after the collision?
