A textbook of mass 1.90kg rests on a frictionless, horizontal surface. A cord attached to the book passes over a pulley whose diameter is 0.150m , to a hanging book with mass 2.93kg . The system is released from rest, and the books are observed to move a distance 1.22m over a time interval of 0.790s .
Part A What is the tension in the part of the cord attached to the textbook?
Part B What is the tension in the part of the cord attached to the book?
Part C What is the moment of inertia of the pulley about its rotation axis?
