A book is at rest on a horizontal table. The table is steadily and slowly tipped until the book begins to slide off the table.
At what angle, in degrees, will the book begin to move?
Give your answer to 1 decimal place.
Details and Assumptions:
The coefficient of friction between the surface of the table and the bottom of the book is 0.5.
You may treat the book as a particle.
You may ignore the effect that the force causing the table to tip has on the book itself.
