2. A girl who passed the dynamics exam enjoys herself swinging in a park with some dynamics textbooks in her hands. The girl has a mass of 50 kg, and each dynamics book has a mass of 1 kg. The distance between the girl's center of mass and the pivot of the swing is 3 m. The two ropes supporting the swing can each withstand 330 N of force without breaking. The girl swings up to an angle 0-30, how many books can she hold at her hands (center of mass) without breaking the ropes?
