A book of mass 7 kg rests on a plank. You tilt one end of the plank and slowly increase the angle of the tilt. The coefficient of statiC friction between the book and the plank is 0.30. What is the maximum angle of tilt for which the book will remain stationary and not slide down the plank? 14.6 Did you draw a free-body diagram and label all forces acting on the book? Consider the positive x direction to be parailei to and down Incline and the y-axis to be perpendicular to the Incline.0 Tutorial Supporting Materials Physical Constants
