Homework Help: Calculate work over a field

  1. Sep 17, 2008 #1
    1. The problem statement, all variables and given/known data
    F=(5y+3x-6)i + (2x-y+4)j. find work done by the force on a particle following a triangular path with verticies (0,0),(4,0),(4,3) where the positions are given in meters.


    2. Relevant equations
    Int(F(x,y))dx*dy ? not really sure for 2 dimensional problems


    3. The attempt at a solution
    I integrated the force equation with respect to x and then y to obtain...
    2xy(5y+3x-3)i + xy(x-(1/2)y+4)j and then calculated the work for each section of the path and added them together. i don't think its the right way to do it though. Is there a way to solve this without the need for line integrals!? Please help

    bump. basically i need to know how to figure out work done over a non uniform 2 dimensional field. even if it requires line integrals, if someone could walk me through it

    nobody knows? did i phrase my question wrong or something?
