How Is Work Calculated When Pulling a Wagon Up an Incline?

Click For Summary

Homework Help Overview

The discussion revolves around calculating the work done when pulling a wagon up an incline, specifically at a 30-degree angle with the horizontal. Participants are analyzing the forces involved and how they relate to the distance moved along the incline.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants are discussing the components of the force applied to the wagon and how to calculate work based on the angle of application. There are attempts to express the work done using vector notation and trigonometric functions. Questions arise regarding the direction of the applied force relative to the movement of the wagon.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the force vectors and their components. Some guidance has been offered regarding the calculation of work, but there is no explicit consensus on the correct approach or interpretation of the problem.

Contextual Notes

There are indications of confusion regarding the angles involved and the direction of the forces, as well as a note about the importance of punctuation in clarifying the discussion. The original poster's calculations and assumptions are being scrutinized.

A person pulls a wagon up an incline that makes an angled of 30 deg with the horizontal with a force on the handle of 30 pounds which makes an angel of 30 deg with the incline find the work done in pulling the wagon 100 ft
20cos30 will be a force along the surface of the incline and since vectors are in the same direction force*distance 20cos30*100=1000sqrt(3) which is the same as if you were to remove the incline?

Do you know about punctuation? Without punctuation it's much more difficult to parse what you have written.

The force applied is NOT in the same direction as the wagon is moving.
 
20lbs 30 degrees
 
The pulling force is being applied at an angle (not angel) of 60 degrees to the horizontal.
 
I would also suppose taking the force vector to be <10,10sqrt(3)>=a and the distance vector <50sqrt(3),50>=b
work= a*b =500sqrt(3)+500sqrt(3)=1000sqrt(3)
but taking the force vector along the incline to be 20cos30 and the distance 100 ft along the incline gives the same results
 
How did you get 20 cos(30 deg)?
