Physics 20 Online
OpenStudy (anonymous):

A student pushes a 0.85 kg textbook across a cafeteria table toward a friend. As soon as the student withdraws the hand (the force is removed), the book starts slowing down, coming to a stop after moving 65 cm horizontally. The coefficient of kinetic friction between the surfaces in contact is 0.38.

a) Draw a system diagram and an FBD of the book as it slows down and calculate the magnitudes of all the forces in the diagram. b) Calculate the work done on the book by the friction of the table.
