Homework Help Overview

The discussion revolves around calculating the work done when pushing an object up a ramp that is 2.6 meters long and 1.1 meters high, with a force of 220 Newtons applied. Participants are exploring the relationship between force, distance, and the angle of application in the context of work done in physics.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are questioning how to properly calculate work done, particularly whether to consider the length of the ramp or the height. There is also discussion about the direction of the applied force and its relation to the motion of the object.

Discussion Status

The discussion is active, with participants providing insights into the nature of the force application and its implications for calculating work. Some have raised questions about the angle of the ramp and the direction of the force, indicating a productive exploration of the problem.

Contextual Notes

There is uncertainty regarding the angle at which the force is applied and whether the height of the ramp should factor into the calculation of work done. The original poster has reiterated the force required to move the object, which is noted as the minimal force necessary for motion.

Homework Statement



If someone is pushing an object up a ramp 2.6m long and 1.1m at the far end how do I calculate total work done?

I know the force needed to push the object is 220N.




Homework Equations




Work Done = Force x Distance

The Attempt at a Solution



Do I do 2.6 x 220 and add this to 1.1 x 220?

Therefore getting 814J?

Thanks

In what direction is the person pushing? Horizontally? Or parallel to the surface of the ramp, i.e. upwards at some angle? Or in some other direction?

Do you know how to calculate work when the force is not in the same direction as the motion?
 
The person is pushing the object up the ramp at an unknown angle.

Presumably I would use Work Done = Force x Distance but do I just use the length of the ramp or do I need to take the height into consideration?

Thanks for the reply

The force needed to push the object is 220 N. That is the minimal force which makes the object moving up the ramp. So it is also directed along the slope.
