Homework 05 > Force Timer Notes EvaluateF Feedback Print Info When you push a 1.63-kg book resting on a tabletop, it takes 2.12 N to start the book sliding. Once it is sliding, however, it takes only 1.51 N to keep the book moving with constant speed. What is the coefficient of static friction between the book and the tabletop? Submit Answer Tries 0/8 What is the coefficient of kinetic friction between the book and the tabletop? Submit Answer Tries 0/8 Send Feedback Post Discussion

Explanation / Answer

A)

F= us (mg)

2.12= us*(1.63*9.8)

us= 0.1327

=========

b)

uk= 1.51/(1.63*9.8)

uk= 0.0945

========

Comment in case any doubt.. good luck
