A 740g, 40cm long rod is free to rotate about a frictionless axle at one end. While at rest, the rod is given a short but sharp 1000N hammer blow at the center of the rod, aimed in a direction that causes the rod to rotate on the axle. The blow lasts a mere 2.5ms. What is the rod's angular velocity immediately after the blow?
