    1. The problem statement, all variables and given/known data

    Someone pushes a book a distance 1.47 m along a horizontal tabletop with a horizontal force of 2.41 N, the opposing force of friction is 0.620 N.

    How much work does force 2.41 N do on the book?
    What is the work done on the book by the friction force?
    What is the total work done on the book?


    2. Relevant equations

    W = Fscos[tex]\phi[/tex]
    W = F * S

    3. The attempt at a solution

    W
    W = 2.63

    Edit:
    Nvm, I got them all/ :D Just realized it.
