Alight string is wrapped around a solid cylindrical spool of radius 0.565 m and mass 1.76 kg. a 5.04 kg mass is hung from the string, causing the spool to rotate and the string to unwind. assume that the system starts from rest and no slippage takes place between the string and the spool. use conservation of energy to determine the angular speed of the spool after the mass has dropped 4.19 m. hint: use the relation v=ïr, and use conservation of energy.
