Question
The options are, one, two, three, four, five, six, horizontally towards the wall, upwards, horizontally away from the wall, downwards, tension, friction, gravity, normal, should, should not, equal to, less than, greater than, the magnitude of the student's push force, the weight of the book.
A student presses a 3.00 kg book up against a vertical wall by exerting a horizontal push force on the book. The coefficients of kinetic and static friction between the book and the wall are Mu k0.350 and Mu s = 0.500, respectively. The coefficients of kinetic and static friction between the book and the student's hand are Mu k= 0.550 and Mu s = 0.700. Determine the minimum pressing force that the student needs to exert in order for the book not to slide down the wall. To answer this question, you first assume that the book does not slide and then draw a force diagram. This diagram contains a total of _______, forces, including gravity (directed ________), the student's push force (a ________, force directed _______), a normal force from the wall (directed ________), and ____ friction forces (each directed ?______). The net force acting on the book ______ be included in the force diagram. The acceleration of the book is _______ ). Applying Newton's second law yields two conclusions: (1) the magnitude of the normal force from the wall is _______ _________and (2) the sum of the friction force magnitudes is _________ After applying the condition for static friction (fs must be __________ fs, max) and doing some algebra, you should find that the student's push force must be N in order for the book not to slide down the wall. The value should be calculated to 3 significant figures.Explanation / Answer
