Reference no: EM13504546

A 0.69 book slides on a horizontal table. The kinetic friction force on the book has magnitude 1.2 .

find:

a) How much work is done on the book by friction during a displacement of 2.7 to the left?

b) The book now slides a distance 2.7 to the right, returning to its starting point. During this second displacement of 2.7 , how much work is done on the book by friction?

c) What is the total work done on the book by friction during the complete round trip?
