Problem $6$: You push your physics book $1\mathrm{.}50$ m along a horizontal tabletop with a horizontal push of $2\mathrm{.}40$ N while the opposing force of friction is $0\mathrm{.}600$ N$.$ How much work does each of the following forces do on the book: $($a$)$ your $2\mathrm{.}40$ N push, $($b$)$ the friction force, $($c$)$ the normal force from the tabletop, and $($d$)$ gravity? $($e$)$ What is the net work done on the book
