Knot To test your understanding of friction, answer the following and write your answers (with complete solutions and labeled free body diagrams) on a clean sheet of paper. Follow your teacher's instructions regarding submission. I. A student presses a 290-gram textbook against a wall as shown in Figure 4. The horizontal force she exerts with her hand is directed perpendicular to the textbook. The coefficient of static friction between the book and the wall is 0.37. For the book to stay stationary and not slide and fall, what is the magnitude of the minimum force that her hand must exert? Figure 4. A hand presses a textbook against a wall
