1. You press a book flat against a vertical wall so that the book begins and remains at rest. The coefficient of static friction for the book – wall interface is 0.6. Assuming that your push is exactly perpendicular to the wall, what is the smallest force you can push with if the book has a mass of 650. grams and is to remain motionless?

Transcribed Image Text:1. You press a book flat against a vertical wall so that the book begins and remains at rest. The
coefficient of static friction for the book – wall interface is 0.6. Assuming that your push is
exactly perpendicular to the wall, what is the smallest force you can push with if the book
has a mass of 650. grams and is to remain motionless?
Expert Solution
Step 1
Given data
The coefficient of friction is given as μs = 0.6
The mass of the book is m = 650 gm.
The smallest force applied to the wall is given as,
Here, N is the normal force, m is the mass of the book, and g is the gravitational acceleration.
