Question
This image shows a book on a table, the normal force acting on the book, and the force being applied to the book. The book is initially at rest, with a static friction coefficient of 0.70 between the book and the table. What happens to the book once force is applied?Select one:The book accelerates to the left.highlight_offThe book moves at a constant velocity to the right.highlight_offThe book remains at rest.highlight_offThe book accelerates to the right.highlight_off
Solution
To answer this question, we need to understand the concept of static friction. Static friction is the force that keeps an object at rest. It must be overcome to start moving the object. The maximum static friction force that can be exerted on an object can be calculated using the formula:
F_max = μN
where μ is the coefficient of static friction and N is the normal force.
In this case, the book is initially at rest, so the force applied must overcome the static friction for the book to start moving. If the applied force is less than the maximum static friction force, the book will remain at rest. If the applied force is greater, the book will start moving in the direction of the applied force.
Without knowing the values of the normal force, the applied force, and the direction of the applied force, we cannot definitively answer this question. However, if the applied force is greater than the maximum static friction force and is applied to the right, the book will accelerate to the right. If the force is applied to the left and is greater than the maximum static friction force, the book will accelerate to the left. If the force is not sufficient to overcome the static friction, the book will remain at rest.
