Two identical books each with k pages are placed on the table in a way that the each page of book A is between the pages of book b. The high half of book B is on top of book A.
Given that 1) the coefficient of static friction on the surface of card A is mu; 2) Each page of the book has a mass of m; 3) Book A does not move from the table. What is the minimum amount of horizontal force applied to book B in order to pull it out of book A?

Solution Summary
This solution includes an explanation and calculations. To pull book B from book A, we have to overcome the static force which is equal to fn*mu. 120 words.
A passenger is pulling on the strap of a 17.8 kg suitcase with a force of 68.9 N. The strap makes an angle of 35.7 degrees above the horizontal. A 38.6 N frictionforce opposes the motion of the suitcase. Calculate the acceleration of the suitcase.
