Question

A student presses a book between his hands, as the drawingindicates. The forces that he exerts on the front and back coversof the book are perpendicular to the book and are horizontal. Thebook weighs 37 N. The coefficient ofstatic friction between his hands and the book is 0.30. To keep the book from falling, what is themagnitude of the minimum pressing force that each hand mustexert? I CANT FIGURE THIS OUT!?!?

Explanation / Answer

we have the force F, from the 1st Law of Newton 2*F*=m*g => F=37.8 N
