  1. Nov 20, 2008 #1
    1. The problem statement, all variables and given/known data
    Find the work done when a constant force F is applied to an object that moves along a vector D where units are pounds and feet


    2. Relevant equations

    F= < 64,36 > D = < 22, -33 >

    3. The attempt at a solution

    I found magnitude by taking square of 64^2 + 36^2. Cant find anything else and dont know where to look!
