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$$\phi$$
W = F * S

3. The attempt at a solution

W
W = 2.63

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