Find friction force, given mass and coefficient of friction

Q: The coefficient of static friction between a book and the level surface it slides on is 0.65. If the mass of the book is 2.0 kg, what minimum initial applied force is required to slide the books across the surface?

A: State what you know.

= 0.65 m = 2.0 kg g . . . → Read More: Find friction force, given mass and coefficient of friction
