A 5 kg block rests on a frictionless horizontal surface. A cord attached to the block passes over the pulley whose diameter is 0.120 m to the hanging block of mass 5 kg. The system is released from rest and the blocks are observed to move 3m in 2.0 s.
A. What is the tension in each part of the block?
B. What is the moment of inertia of the pulley?
