A rod with a length of 1.0 m and a mass of 7 kg can freely rotate around a horizontal axis passing through its upper end. A bullet of mass m = 10.0 g, flying in a horizontal direction with a speed V0 = 500 m/s, hits the lower end of the rod and pierces it. With what angular velocity will the rod begin to move immediately after the impact if the bullet flies out of the rod with a velocity V1 = 200 m/s?
