Question: A string is wound around a uni radius 0.4 m and mass 3 kg. The disc is released from rest with the string vertical

A string is wound around a uni radius 0.4 m and mass 3 kg. The disc is released from rest with the string vertical and its top end tied to a fixed support. h F: 3 kg W 0.4 m Calculate the speed of the center of mass when, after starting from rest, the center of mass has fallen 3.1 m. The acceleration of gravity is 9.8 m/s. Answer in units of m/s.
