Answer 1

Concepts and reason

The concept used to solve this problem is related analyzing the forces acting on the object in motion.

First, identified the forces acting on a body when it is sliding on the surface. Then choose the appropriate forces and finally, discard the other forces acting on the body.

Fundamentals

A force is a push or pulls acting upon an object as a result of its interaction with another object. There are various types of forces. These forces are divided into two broad categories namely contact forces and non-contact forces.

When the net external force exceeds the maximum static friction, then the body starts to move and the force due to friction acting on the body is known as kinetic friction.

A force is a push or pulls acting upon an object as a result of its interaction with another object.
‎

In the given system, the object is in motion and it is sliding on the surface. So, kinetic friction is act on the book. It is because the static friction act on the object if object at rest.

The spring force is related to the compression or stretching of spring. Normal force is the component of the contact force exerted on the body perpendicular to the surface.

The drag force acts on the object when the object in some type of fluid.

The force due to tension describes the pulling force.

Gravity is the force which is acting on objects having mass. It is the due to the gravitational force of earth.

In the given system, the book is in motion. Kinetic friction act on it.

There is no spring associated with it. So, no spring force is present there.

The normal force acts on the object. The normal force is equal to the weight of the object.

There is no fluid. So, no drag force present.

Also, there is no pulling force in the given system. So, the tension is not present in the system. But book have mass. So, gravity acts on the book.

Hence, the forces acting on the book are kinetic friction, normal force and gravity.

Ans:

The forces acting on the book are kinetic friction, normal force and gravity.
