Answer
Which of the following describes velocity? (1 point)

Velocity is the resistance of an object to a change in its speed or direction.

Velocity is a force that changes an object's speed and/or direction.

Velocity is the sum of all of the forces acting on an object.

Velocity is the speed of an object in a particular direction.

According to Newton's First Law of Motion, an object in motion will stay in motion at the same speed and direction unless acted upon by **an unbalanced force**.

To find the net force, we subtract the air resistance force from the running force because they are acting in opposite directions.

Net force = Running force - Air resistance force
Net force = 325 N (to the right) - 45 N (to the left)
Net force = 325 N - 45 N = 280 N (to the right)

So, the net force of the runner is **280 N**.

To determine the direction in which the book will move, we need to find the net force acting on it.

The net force is calculated as follows:

Net force = Pushing force - Frictional force
Net force = 7 N (to the right) - 3 N (to the left)
Net force = 7 N - 3 N = 4 N (to the right)

Since the net force is 4 N to the right, **the book will move to the right**.
