Question
When you push a 1.77 kg book resting on a tabletop, it takes 2.29 N to start the book sliding. Once it is sliding, however, it only takes 1.45 N to keep the book moving with a constant speed.A) what is the coefficient of static friction between the book and tabletop ?
B) what is the coefficient of kinetic friction between the book and the tabletop? When you push a 1.77 kg book resting on a tabletop, it takes 2.29 N to start the book sliding. Once it is sliding, however, it only takes 1.45 N to keep the book moving with a constant speed.

A) what is the coefficient of static friction between the book and tabletop ?
B) what is the coefficient of kinetic friction between the book and the tabletop?
Explanation / Answer
static friction=2.29 N
static friction coeffciient=2.29/(1.77*9.8)=0.132
b)kinetic friction =1.45 N
kinetic friction coefficient=1.45/(1.77*9.8)=0.083
