A textbook of mass 2.05 kg rests on a frictionless, horizontal surface. A cord attached to the book passes over a pulley whose diameter is 0.190m, to a hanging book with mass 2.94 kg. The system is released from rest, and the books are observed to move a distance 1.29m over a time interval of 0.760s.
1) What is the tension in the part of the cord attached to the textbook
? in N
2) What is the tension in the part of the cord attached to the book?
in N
3) What is the moment of inertia of the pulley about its rotation axis? (freefall acceleration to be g = 9.8 m/s^2)
kg*m^2
