Question

A physics textbook weighing 22N rest on a table. The coefficient ofstatic friction between the book and the table is 0.60 and thecoefficient of kinetic friction is 0.40. You push horizontally onthe book with a force of 15N. A) What is the magnitude of the force of friction B) State wether the book is accelerating, decelerating, atrest or moving with constant speed. A) What is the magnitude of the force of friction B) State wether the book is accelerating, decelerating, atrest or moving with constant speed.

Explanation / Answer

    Given    weight of thebook    =   mg   = 22 N   a )     if the book is atrest   the friction is static friction            here the force of friction is                    f   = s mg                        = 0.6 * 22                        = 13.2 N       force applied on the book F = 15 N                 force of friction                         f   = F + k mg                            = 15 + (0.4 * 22 )                             = 23.8 N
