A cord attached to the book passes over a pulley whose diameter is 0.150 m, to a hanging book with mass 2.00 kg. The system is released from rest, and the books are observed to move 1.20 m in 0.800 s. What is the moment of inertia of the pulley about its rotation axis? 10) A frictionless pulley has the chann e
