Answer:
9.4 N
Explanation:
m = mass of the book = 1.83 kg
= Coefficient of static friction = 0.522
= Coefficient of kinetic friction = 0.283
= Static frictional force
F = force needed to make the book move
force needed to make the book move is same as the magnitude of maximum static frictional force applied by the desk on the book
Static frictional force is given as
=
mg
Hence, the force need to move the book is given as
F = =
mg
F = mg
F = (0.522) (1.83 x 9.8)
F = 9.4 N
