44. Flat rod with a mass M = 6.0 kg and a length l = 2,0 m can rotate in a vertical plane about a horizontal axis passing through the point O (Fig.). At the end of the rod gets the bullet mass m = 10 g, flying at a speed of υ0 = 1,0 ∙ 103 m / s directed perpendicular to the shaft and gets stuck in it. The kinetic energy of the rod after the impact.
