the weight of the book is 1.92 * 9.81 = 18.8N
Now, how is friction determined?
When you push a 1.92 kg book resting on a tabletop, you have to exert a force of 2.0 N to start the book sliding. Once it is sliding, however, you can use a force of only 1.0 N to keep the book moving with constant speed. What are the coefficients of static and kinetic friction between the book and the tabletop?
