Chapter 5: Q. 37 (page 129)

Problems 35 through 40 show a free-body diagram. For each:
a. Identify the direction of the acceleration vector $\overset{鈫�}{a}$ and show it as a vector next to your diagram. Or, if appropriate, write $\overset{鈫�}{a} = \overset{鈫�}{0}$
b. If possible, identify the direction of the velocity vector $\overset{鈫�}{v}$ and show it as a labeled vector.
c. Write a short description of a real object for which this is the
correct free-body diagram. Use Examples 5.4, 5.5, and 5.6 as
models of what a description should be like.

Short Answer

Expert verified

A free-body diagram is a pictorial representation of an object that represents all the forces acting on the object.

Step by step solution

Part a Step 1: Identifying the acceleration vector

In the given free-body diagram, only the force due to gravity is shown here. Therefore, the acceleration vector should be directed along downward.

Labelling the acceleration vector

The acceleration vector is shown in the given diagram:

Part b Step 1: Identifying the velocity vector

There is only a single force, which is the force due to gravity. Therefore, direction of motion cannot be determined only with this data.

Description of a real object

According to the given diagram, there is only one force in action that is the force of gravity ${\overset{鈫�}{F}}_{G}$ . Therefore, the net force is acting directly downwards. We can describe the given situation as if a ball is dropped from a ten storied building. So, only the gravitational pull acts on the ball as shown in the free-body diagram.
