Atextbook of mass 2.10 kg rests on a frictionless, horizontal surface. a cord attached to the book passes over a pulley whose diameter is 0.100 m , to a hanging book with mass 2.99 kg . the system is released from rest, and the books are observed to move a distance 1.26 m over a time interval of 0.790 s . part a what is the tension in the part of the cord attached to the textbook? =9.66n part b what is the tension in the part of the cord attached to the book? take the free fall acceleration to be = 9.80m/s^2 =15.5n part c what is the moment of inertia of the pulley about its rotation axis? take the free fall acceleration to be = 9.80 m/
