A student holds a physics book in her hands motionless 1.2 meterabove the floor as shown to the left. The forces from her hands onthe front and the back of the book are perpendicular to the book'scover and are horizontal. The mass of the book is 30 kg. Thecoefficient of static friction betweent the covers and her hands isµs=0.49 and the coefficient of kinetic friction is µk=0.3.
c) What is minimum normal force that the student can apply fromeach hand to the cover of the book to keep it from slipping throughher hands?
