I have a question i cant get?

ou push your physics book 2.40 m along a horizontal tabletop with a horizontal push of 2.30N while the opposing force of friction is 0.600 N.How much work does your 2.30 push do on the book?How much work does the friction force do on the book?How much work does the normal force from the table do on the book?How much work does gravity do on the book?What is the net work done on the book? ALL IN JOULES
