Expert Solution & Answer
Answer to Problem 9TE
The force of friction acts on a book is 1 N.
Explanation of Solution
Galileo states that a force is needed only to start the motion of an object, but after moving, no force is required to keep a body moving except for the force required to overcome friction. For example, only a starting force is required to move an object on a frictionless surface and it moves continuously further.
A of force applied on a book horizontally that moves a book at a constant velocity. The book's initial force is only able to start the book's movement, and it moves at a constant velocity further, which means that the force of friction is offered to the book is equal and opposite to the horizontal push. This friction force cancelled the horizontal push force and made a book to moving with a constant velocity from conditions of equilibrium. So, from the above results, it is concluded that the force of friction acting on the book is 1 N.
Conclusion:
Therefore, the force of friction ats on a book is 1 N.Chapter 3 Solutions
