Horz./vert. components of force

In summary, the conversation discusses a problem involving a man pulling a trunk up a ramp with a slope angle of 20.0. The man exerts a force of 381N at an angle of 30.0 with the ramp. The conversation also mentions the need for help and confusion on obtaining the components of the force. One person suggests rotating the axis to match the ramp's axis and calculating the gravitational and pulling forces. The other person reveals that they were able to solve the problem with an x component of 245N and a y component of 292N. They also mention the use of algebra in their solution.

Homework Statement


A man is dragging a trunk up the loading ramp of a mover's truck. The ramp has a slope angle of 20.0, and the man pulls upward with a force of magnitude 381N whose direction makes an angle of 30.0 with the ramp.

Im in need of some help I can't seem to figure out how to get each component of the force I know each has its own force in the x and y

I would start off by rotating my axis so they match with the ramp axis, which I'm sure you have done in class, then figure out the gravitational force down the ramp and the pulling force up the ramp. If you want more help you will have to be more specific and show what part you are stuck on.

hmm actually no i never rotated the axis i couldn't figure out how to solve the problem. i ended up with the answers I am just trying to get an idea of how it was solved. I got 245N for the x components and 292N for the y

You must have done a lot of algebra then, but you ended up with the right answer (good if so)? Can I see what you did?
 

FAQ: Horz./vert. components of force

What is the difference between horizontal and vertical components of force?

The horizontal component of force is the component of force that acts parallel to the ground, while the vertical component of force is the component that acts perpendicular to the ground.

How do you calculate the horizontal and vertical components of force?

To calculate the horizontal and vertical components of force, you can use trigonometric functions such as sine, cosine, and tangent. The horizontal component can be found by multiplying the force by the cosine of the angle between the force and the horizontal axis. The vertical component can be found by multiplying the force by the sine of the angle.

What is the importance of understanding horizontal and vertical components of force?

Understanding the horizontal and vertical components of force is important because it allows us to analyze the motion of objects in two dimensions. It also helps us to determine the net force acting on an object, which is essential in understanding its acceleration and overall motion.

How do the horizontal and vertical components of force affect an object's motion?

The horizontal component of force affects an object's motion in the horizontal direction, causing it to speed up, slow down, or change direction. The vertical component of force affects an object's motion in the vertical direction, causing it to rise, fall, or remain at a constant height.

Can the horizontal and vertical components of force cancel each other out?

Yes, the horizontal and vertical components of force can cancel each other out if they are equal in magnitude but act in opposite directions. This will result in a net force of zero and the object will not experience any acceleration in either direction.
