A woman holds a book by placing it between her hands such that she presses at right angles to the front and back covers. The book has a mass of m = 1.7 kg and the coefficient of static friction between her hand and the book is μs = 0.53. What is the weight of the book, Fgb in Newtons? What is the minimum force she must apply with each of her hands, Fmin in Newtons, to keep the book from falling?
