SUMMARY

The discussion focuses on calculating the work done by a shopper pushing a cart with a force of 35N at a 26-degree angle downward from the horizontal over a distance of 50.7m. The correct formula for work is w = (f)(cos θ)(Δx), where θ is the angle of the force. The user initially misapplied the formula and sought clarification on the correct approach to solve the problem. Reference material was provided to assist with similar problems.

PREREQUISITES
  • Understanding of basic physics concepts, specifically work and energy.
  • Familiarity with vector components and trigonometric functions.
  • Knowledge of the formula for calculating work done (w = f * cos θ * Δx).
  • Ability to interpret and solve word problems in physics.
NEXT STEPS
  • Review the concept of work in physics, focusing on the formula w = f * cos θ * Δx.
  • Study trigonometric functions and their application in resolving forces into components.
  • Practice solving similar physics problems involving angles and forces.
  • Explore additional resources on work and energy, such as online physics tutorials or textbooks.
USEFUL FOR

Students studying physics, particularly those tackling problems related to work and energy, as well as educators seeking to provide clarity on these concepts.

Homework Statement



a shopper pushes a cart with a force of 35N directed at an angle of 26' downward from the horisontal.

find the work done if he pushes the cart for 50.7m



Homework Equations



w=(f)(cos 0)(Δx)
f= w/(cos 0)(Δx)

The Attempt at a Solution



i did but i got it wrong
i did: the equation and got it wrong then i tried to find force because i though it was a word problem but was not successful please help

Are you sure you get it wrong. http://mravis.com/planbook/PreAP%20Physics/Jan082008/PAP%20Work%20and%20Energy%20WS.pdf" you have got similar problem (number 7).
