Question

A box is being pulled to the right the free body diagram is shown What is the magnitude of the kinetic frictional force? 25 N 125 N 375N 500N​

Answer 1

Without the actual Free-Body Diagram or additional details, we cannot accurately determine the magnitude of the kinetic frictional force on the box. The reference mentions a frictional force of 45.0 N, which may infer the answer if related to the same situation.

Step-by-step explanation:

In the given reference material, a kinetic frictional force of 45.0 N implies that the normal force and the coefficient of kinetic friction have already been accounted for. Therefore, assuming the reference material is related to the question, we might infer that the magnitude of the kinetic frictional force being asked is 45.0 N. Otherwise, without more specific details from the actual Free-Body Diagram or additional information about the mass of the box and the coefficient of kinetic friction, we cannot accurately determine the magnitude of the kinetic friction force.

Answer 2

In this case, the magnitude of the kinetic frictional force is 25 N.

the correct answer is:1) 25 N

Step-by-step explanation:

To determine the magnitude of the kinetic frictional force, we need to analyze the free body diagram provided.

The four forces acting on the box are as follows:

• 1. A force pointing north with a magnitude of 438 N.
• 2. A force pointing northeast with a magnitude of 125 N.
• 3. A force pointing south with a magnitude of 500 N.
• 4. A force pointing west with a magnitude of 25 N.

The kinetic frictional force acts in the opposite direction of the motion. In this case, since the box is being pulled to the right, the frictional force acts to the left.

Looking at the free body diagram, we see that the force pointing west with a magnitude of 25 N is the only force acting in the opposite direction of the motion. Therefore, the magnitude of the kinetic frictional force is 25 N.

So, the correct answer is:

option 1- The magnitude of the kinetic frictional force is 25 N.

Your question is incomplete, but most probably the full question was:

A box is being pulled to the right. The free body diagram is shown.

A free body diagram with 4 forces. The first pointing north labeled 438 N, the second pointing northeast labeled 125 N, the third pointing south labeled 500 N, and the fourth pointing west labeled 25 N.

1. 25 N
2. 125 N
3. 375 N
4. 500 N
