A book of mass 5.2 kg is resting on a flat level table. You push down on the book at an angle of 25.0 degrees from the horizontal with force of magnitude 236 N. The book starts to slip and is sliding across the table. What is the magnitude of the force of kinetic friction from the table on the book? The coefficient of kinetic friction between the table and the book is μk = 0.43.
