   1. The problem statement, all variables and given/known data
   
   A particle moves from the origin to the point x=3m, y=6m along the curve y=ax^2 - bx , where a = 2.0m^-1 and b = 4.0m . It is subject to a force F=cxy i + d j , where c= 8.0N/m^2 and d= 16N .
   
   2. Relevant equations
   
   Calculate the work done by the force
   
   3. The attempt at a solution

   Work is defined as:
   
   [tex]\int\vec{F}d\vec{x}[/tex]. Do you know what's next?

   Take the integral of work.
   
   [tex]W=\int Fds \rightarrow W = \int\int F dx dy[/tex]
   
   Catch my drift?
