How Do You Calculate the X and Y Components of a Force?

In summary, the conversation discusses a dog pulling on a pillow with a force of 7.9 N at an angle of 28.3 degrees above the horizontal. The formula for net force is mentioned and two questions are asked: the x component of the force and the y component of the force, both to be answered in units of N. It is suggested to draw a free-body diagram and break the vector into its x and y components to find the solutions.

A dog pulls on a pillow with a force of 7.9 N at an angle if 28.3 degrees above the horizontal

[tex]\vec{F}_{net} = \Sigma \vec{F} = m \vec{a}[/tex]

A) What is the x component of this force?
answer in units of N.

B) What is the y component of this force?
answer in units of N.


help pls i can't find a way.
and I am not a drawing kind of guy. thanks for any help like step by step

First, before we can even help you, you need to show your attempt at the solution. Second, whether or not you're a "drawing kind of guy", you'll have a difficult time doing a lot of physics problems without first drawing a free-body diagram. So, draw a free-body diagram and then show your attempt at a solution!

Show what you tried so people can help with what you are misunderstanding.

If you have no idea at least try to draw a picture for yourself, it will help.

You have a vector and you have its direction, now you just need to break it into an

x and y component. The x an y form the legs of a triangle and the Net vector is the

hypotenuse. See what you get.

1. What is a net external force?

A net external force is the sum of all external forces acting on an object. It is the overall force that is responsible for causing a change in an object's motion.

2. How do you calculate net external force?

To calculate net external force, you need to determine all the external forces acting on an object and then add them together. This can be done using vector addition, where you consider the magnitude and direction of each force.

3. What are some examples of external forces?

Some examples of external forces include gravitational force, frictional force, applied force, and normal force. These forces can either push or pull on an object and can vary in magnitude and direction.

4. How does net external force affect an object's motion?

Net external force determines the acceleration of an object, which in turn affects its motion. If the net external force is zero, the object will remain at rest or continue moving at a constant velocity. If the net external force is non-zero, the object will accelerate in the direction of the force.

5. How is net external force related to Newton's laws of motion?

Net external force is directly related to Newton's laws of motion. The first law states that an object at rest will remain at rest, and an object in motion will continue moving in a straight line at a constant speed, unless acted upon by a net external force. The second law explains how net external force affects an object's acceleration, and the third law states that for every action, there is an equal and opposite reaction force.
