Question

Exercises 22 show a free-body diagram. Write a short description of a real object for which this would be the correct free-body diagram. Use Examples 5.4, 5.5, and 5.6 as examples of what a description should be like.

Short answer

The free body diagram is a pictorial representation of an object under some forces where the object acts as an particle and the forces acting on the object.

Step-by-step solution

Given information:

The object is represented by the dot according to particle model.

The force of gravity F_G acts downwards along negative Y-axis.

The normal, n , is acting upward along positive Y-axis.

The kinetic friction f_k acting leftwards along negative X-axis.

The net force is acting along leftwards.

Writing the real object situation that described the given free body diagram:

Example 5.22 best describes the given free body diagram.

"A baseball player is sliding into the second base"

Here, the player is represented by the dot.

The normal force acts upwards.

The kinetic friction arises due to the sliding.

The force of gravity is due to its mass.

The net force is along the kinetic friction.

Therefore,$F_{net}=f_k$
