| Two concentric disks each of mass M=5 kg and radius R1=15 cm and R2=65 cm form a rigid body that is free to rotate about the center axis. Two blocks each of mass m=2.75 kg are suspended by ropes that are respectively wound around the rim of each disk. The system is released from rest and the block attached to the larger disk has moved by an amount h=20cm Assume that the ropes move without slipping and the blocks move only vertically. Take gravitational acceleration g=9.81m/s^2 1) Calculate the speed of the block attached to the smaller disk when the block attached to the larger disk moved by an amount h after the system was released from rest. |
